Why do I have sudden battery drain?

Why do I have sudden rapid battery drain?

Davidhye is correct. The screen at lower contrast is hardly readable. That's why I said the screen quality is extremely bad. Even at 00% contrast, it is hard to read in bright neon light. It only has good readibility with rather dim light. At 50%, I almost can't read the text at all. At 0-20%, I don't think anyone can read it.By contrast, without trying to promote iRi'ver at all, my H320 has 0 steps of contrast. At 0, the screen displays text?even sharper than my Dell LCD monitor. At 50%, the text is highly readible, because only the color looks worse. Brightness at 0% (yes ZERO %), the text is as readable as ZMP at 00% contrast....believe it or not.
Even funnier, at bright day light, iRi'ver at 0% contrast is still much more readible than ZMP at 00% contrast.
Never did I imagine the ZMP screen can be that bad. About the battery, I played at normal (no equalzr) at vol 7. I asked ZMP buyers from the same seller (we bought it from a classified in a local forum), and they all have the same problem. The battery life is only about 7-8 hours max from the claim of 5 hours by Creative. I played my H320 skipping all around my music folder like crazy for?2.5?hours today, and .... I'm so proud to say, it has not even down notch !!!. Geezzz what a difference.

Macbook w 153 cycles why do i have service battery?

macbook white with 153 cycles . Why do i have service battery?

If the phone is within its one year warranty the battery replacement should be free. If Apple tests it and says it is defective. If their test says it is not defective then you have a software problem that can be fixed.

Xperia Z3 sudden battery drain

Hi, I am new new to the forum and this is my first post.
I have an Xperia Z3 D6653. Lately I have been noticing that the battery has been draining faster than normal. I installed a battery analyzser app for that too.
A few observations:
The battery drops from 12% to ~4% in matters of seconds.
When the phone is on charge at 96% it jumps to 99% and comes back to 97% and then again 99% and suddenly 100%. This was using the wall charger.
The main point which made me write this post was my idle drain. I sleep with my phone 100% and wake up at 52%. My WiFi auto sync and GPS was on. No bluetooth or NFC.
I understand there is battery drain but 48% is not understandable.
Thanks in advance.

Hi
Since google play services is using the maximum battery, it's for sure that one of the app is the culprit. ( in the second screenshot, apps usage is 74% of the total battery used )
Uliwooly gave the best possible way to determine it.
Usually a normal phone restart could also help fix the problem.

MBA 2013 screen crash and suddenly battery drains

Hello, I bought MacBook Air November 2013 in India. I am facing the same problem in my MBA after 6-7 days of buying date. Since it is my first device from Apple so I am following all instructions by the reseller and service center persons.
First I spoke to the reseller, he suggested me sometimes due to third party apps it may happen. When it happened again then he suggested me to go to service center. In between that I joined the discussion on Apple support community and started to get the comments about this issue. Then I chatted online with apple persons they instructed me to check settings of SMC and PRAM and suggested to go to service center. Then after, 3 times I have taken my MBA to service center:
1st time: they changed the settings in it and gave back to me by saying to observe the problem.
I observed it for 2 days and problem occurred. I informed to service center.
2nd time: they kept it for 4 days with them to observe and gave it back by saying that we have fresh installed the Mac OS10.9 since this issue was due to I have updated the Mac OS from 10.9 to 10.9.1
Within 4-5 days it happened again with one more problem of showing battery drain significantly by spot light. I continued to observe these issues for few more occurrences. In between that again I chatted with apple person and discussed both the issues.... amazing... again he told me the same settings as previously and observe.
3rd time: I took it to service center and told compete issue about the discussion with apple persons too. They kept it for two days and simply said that we have to chat with Apple technicians then only we say something. They chatted with Apple technicians and suggested me to keep the machine as it is till the Apple people update the firmware… When I asked… How much time it will take…? They said, “Do not know”!
Interesting point is that in front of service center person I showed this issue how screen crashes and how the battery drains happening and showing energy used significantly by spotlight. Even then those persons told me to wait for firmware update by Apple.
After take from service center, one more thing is happening with my MBA if I put my finger in front of webcam brightness of display goes dim. I do not know, how the service center persons are dealing?
When I asked to replace it or upgrade it to another machine then they simply raise their hand and we can do nothing for this. And told you have to speak with Apple persons
Now what to do? I am helpless…!!!

After take from service center, one more thing is happening with my MBA if I put my finger in front of webcam brightness of display goes dim. I do not know, how the service center persons are dealing?
Thats 100% normal, thats auto-dim as it senses the light. All of them do that.
As for the rest, your Air is in for service, this is a users board, contact Apple Inc. about any issues regarding your service calls.

Xperia Z1 sudden battery drain

Ive had my Xperia Z1 for just over a year and for the last couple of weeks I have had an issue where the battery will go from 30% to 10% and then power off in a few minutes. Sometimes it will be at 25% and then power off saying 0%
I have followed the advice on here, tried repairing etc through Sony bridge for Mac. I have spent all afternoon reinstalling and reconfiguring all of my apps and my phone has just gone from 25% to 0% and powered off
How is it that people are still having this issue? Surely someone must be able to provide an answer that works.
I find it incredible that a company like Sony are unable to provide an answer to a problem that a lot of people seem to be having...

Sorry i don't mean to hijack the thread but wanted to chime in that i have exactly the same problem over the last two months. For example i had 83% charge which then fell to 45% and then the phone had instant battery drain.
No unusual apps running, just browsing the net and pandora in the background.

Ipod touch 4g sudden battery drain

Greetings all,
Ill get straight to the point..
ive bought the ipod touch 4g barely a month ago, and since then ive been experiencing the following battery issues..
1. Random battery drains (put to standby for 4 hours, click it on, only 1 or 2% battery lost, however within seconds, in front of me, the battery drops another 10% without me even touching the screen).
2.I had the screen brightness at 50% no wifi/bluetooth on, with auto brightness...
3. The same video which takes 4%, sometimes takes 12-15%, at the exact same settings with no apps or anything else on...
4. Sometimes when the battery is at 97% or so, charging, i disconnect it...and immediately it jumps to 100%, i play music for a minute and it returns to its actual level which is 97%...
4. I have tried restoring several times...to no avail..problem persists...
Since i had no clue about the apple return policy(being new to apple products), i missed my chance to get an immediate replacement, and i was asked to send it to an apple service centre...which kept it for a day, ran two hours of video and said the battery life was normal since it drained just 30% as it should have..
These battery level drops happen completely randomly...however they are worrying me a great deal....
Is there any way to get a replacement under the warranty?
They are not easy to reproduce, as is the very nature of the problem, and i seem to have missed out on the return policy.
If there is any way to get a replacement, for a brand new faulty ipod touch 4g, with such a random but crippling ailment, i wouldnt mind paying 20% of the price , if thats what it takes, I am that desperate.
Would be grateful for any help by apple experts on this!

On a Side note: my friend with another ipod touch 4g(32 gb, same as mine), has no such issues.

Anyone else have terrible battery drain since the update?

I did the update yesterday morning and right away started to notice battery drain.. Before that I had the best battery of any iphone I've ever had. I have the 5s currently. I changed nothing so there should be no change in my battery usage so the only thing it could be is something with the upgrade. It's probably too early since the update came out to know what the problem is and I guess I should have waited to do it till the bugs were worked out. Other then that I have found no problems. Anyone else having the battery drain problem?

I'm sure there are people who had battery drain after updating to 7.1.1. I'm sure because there are people who posted about it, and you could have found out yourself just be reading the forum or searching it. How does knowing that help you?
I'm also sure there were people who had extra battery drain after updating to 7.1, and to 7.0, and to 6.3, and to 6.2, and to 6.1, and to 6.0, and to 5.4, and to 5.3...all the way down to 1.1. Again, because they posted and said so.
For the record, my battery usage hasn't changed since updating.
You are wrong that the only thing it could be is the upgrade. If it were the upgrade there would be 10,000 or more posts about it already.
However, sometimes the process of upgrading "confuses" some apps, and they run continuously trying to recover. This drains the battery rapidly. To solve the problem take basic troubleshooting steps, and stop once the problem is resolved:
Turn the phone off by holding the SLEEP button until slide to power off appears; wait a few minutes, then turn it back on
Restart iOS by holding HOME and SLEEP until an Apple logo appears (10-15 seconds)
Kill all running apps - double press the HOME button, and flick each screen image up. Then restart the phone again
Restore the phone using iTunes on your computer
Usually one of these will fix it. Post back if none of them work.

Do any Samsung WP owners have their battery drain to dead while powered off?

I've noticed my ATIV SE battery drains completely dead while powered off in just a couple days. It has a nearly full charge when powered off and then when I go to power it on, it's dead.

It started in September which was about 2 months after purchasing the phone. It's a recurring issue. Yes, in my example, the phone is completely powered off for the full two days. More specifically, the trend is I turn my phone off for about 10 hours and when I turn it back on it's lost about 12-14% battery charge. Since posting my question, I've sent it back to Samsung Support for repair (on the second go-around now). They replace the battery (supposedly) the first time. The issue was worse after that. The battery would lose about 21% charge in just 12 hours of being powered off. The current Samsung repair log states they've replaced the PBA, updated software, and further repair is pending a hardware part (unknown) replacement.

Why is my ipad 2 battery draining so fast HELP!!

I use my ipad 2 for work every day. I got it about 3 years ago (15 days after starting my new job) i charge it every day like normal. But now it runs out very fast aspecially when my son watches movies on Netflix, it only lasts 40 minuets and I gets really shouted at at my boss. HELP

I just received my first ipad2 after using my sisters iPad. I am still setting it up and realized I have had to recharge my battery after a very short time. my sister used her iPad constantly in the last year and she only charged her iPad upon receiving it.She is only now going to have to recharge it for the 1st time in a year! I am thinking my battery has to be defective to drain so quickly, and I don't want to be saddled with a lemon!

Sudden battery drain

I love my Blackberry Curve BUT I've had untold problems since I got my first one, 2 replacements already and not a particularly heavy user.
Anyway, now over the last couple of days, my battery is draining during only 24 hours and I'm not even using it loads, picking up emails and made a few calls, but nothing excessive.
I've only had this particular one since December. Mind you they might have put my old battery in it, so the battery might be a year old.
Any ideas?
Also anyone else have this many problems? I'm so frustrated, I love the functionality of Blackberry but finding the reality very frustrating. Thinking of jumping ship in Sept when I'm due an upgrade. So it's between the Storm and an iphone.

Here are some good charging tips, please read and you'll see that many of them will apply to you.

Sudden battery drain/not charging/lost Wifi

Hi, Over the last 24 hours i've notice my Xperia Z2's battery is draining very quickly, even when asleep. Even when it is plugged in charging, i keep getting messages saying the phone is unable to charge as it is using too much power. And previously i could charge the phone overnight fully, now it doesnt get close to 40% In addition to this ive noticed it is kicking out a lot of heat at the top of the phone, and also i can no loger connect to the internet via wifi. Everything else seems ok, and i have managed to back up my data to an sd card. I havent added any new apps recently. I've had the phone for less than a year and as far as i know it hasnt had any heavy drops or anything. Has anyone got any cheap fix ideas or will it need to be sent of for repair? Thanks in advance Simon

Hi Simon, first thing i would do is try running it in Safe Mode fo a while.....even tho you've not added any new Apps lately there could be one acting up, Sfe Mode will determine this............if no difference then my next step would be to do a PCC Repair but just double check that you do as mentioned have everything backed up.

Raxr M Sudden Battery Drain

I was getting great battery life until the last two days. Wifi is using between 25 - 30 %, I notice on the wifi indicator that it is sending and receiving every few seconds. I was getting three days easily on a charge now only a little over a day. I haven't added any apps or changed anything I did a couple of updates the other night. I had trouble one day with the Accuweather circle, it wasn't updating the time and temp; I rebooted the phone and it started working. I checked the running apps and don't see anything out of the ordinary.

Mine has been good since I moved and rebooted the router at work. If you go into your settings and go to battery, then if you touch the basic graph it will take you to a more detailed graph and you can see if the drain is worse at certain times. Also go into data and see if any apps are using a lot of data, also go into settings and check show wifi and it will show which apps are using the most wifi. You could have an app that is running and draining the battery. I noticed Google+ used a lot of data and I hardly use it at all so I logged out and that seemed to help.

Why does my iPhone 5 battery drain so fast!?!?

Got an iphone last week.. for every minute that my screen was on, my battery would drain 1%. I was charging it so many times a day.. you can do the math. Finally brought it to Apple after day 3 and they gave me a brand new phone. My new one is doing the same thing.. I find it unlikely that I'd get TWO defective phones in a row. My friends with the iphone5 say they can go about a day and a half with heavy usage and still have a small battery percentage left. Is there something I'm doing wrong? I only have about 4 apps and I close them out completely when I'm not using them. I barely use the browser... I text a lot but isnt that the purpose of having a phone? Help please! Very displeased with Apple right now.

You could set it to Fetch every 15 minutes and see how your battery holds up. I have it set to check manually and when I open email it downloads the mail then.
It's not a great solution if you need Push email but it saves the battery.
Apple needs to fix it, it seems anything that uses networking is broken in iOS 6. iOS 6.0 and 6.0.1 function like beta versions of software.
Looking at the discussion forums Apple can and should do better than this. If serious users cant connect to wifi properly, cant get acceptable download speeds, see their cellular data usage skyrocket and cant use push emails then the iPhone 5 becomes an expensive toy.

Why is my ipod touch battery drain out so fast

My ipod touch is 4g 8gb and I had it for two years, it is also ios 6.1.6 . I bought my ipod in 2013 and it was working great, but later on in the second year it wasn't. Every time it was fully charge and I take it out of the charger in one second or five sec the battery level would move very fast and then shut down and say it is low in battery. I can't use my ipod without plugging it in my charger or else it would shut down in like 5 sec when I am on it. I always close open apps and I tried resetting my ipod settings but nothing work. I don't know if it was the soft ware update to ios 6.1.6 that caused the battery to drain out so fast, but I don't know what is causing this problem.

As Skydiver said, if only the battery is bad
Apple will exchange your iPod for a refurbished one for $79. They do not fix yours.
Apple - iPod Repair price
A third-party place like the following will replace your batter for less. Google for more.
iPhone Repair, Service & Parts: iPod Touch, iPad, MacBook Pro Screens
Replace the battery yourself if you are up to it. A replacement battery costa about $15

Does anyone know why my iPod Touch 5G battery drains in less than 4 hours?

Hello fellow Apple users. I am having battery issues with my iPod Touch 5G. It's only 6 months old and already the battery is draining quickly. It used to last me around 9-10 hours on a single, full charge (on iOS 6) Playing with games didn't affect the battery very much, so I'm assuming there's a battery bug with iOS 7? If not, may I please hear your suggestions?

You may want to poke around in notifications. There's a ton of stuff defaulted to on that you may not need. As well as background app refresh and background app update. When those are on your iPad regularly reaches out to get more info and that can affect your battery.
