Re: HTC Rezound update has shortened battery life and causing device to run hot anyone having issues?

budone pointed me in the right direction but I think tidbits pushed him off with apps and clearing cache. Battery app definitely showed me what the issue was.
Battery monitor and phone built in monitor shows phone call usage above 25%. I don't use my phone for hours a day (320 minutes / 4 = 80 minutes talk time). So why is my phone polling Verizon towers so often? Issue also prevented phone from sleeping correctly. So, SIM/firmware conflict. The update pushed a radio setting in the phone to a CDMA + LTE/EvDO auto which was to correct the SIM/reboot issue.
Thread detailing boot loop issue and fix, forum.xda-developers.com/showthread.php
My phone was already set to a correct radio setting prior to the update. When the update was pushed I had my phone in 3G/CMDA to maintain the battery. This update forced a setting and restarted phone and caused a SIM/firmware conflict. Now my phone will go into a boot loop when it drains below 20% and in CDMA(3G). 4G LTE it will run fine. Why? Still attempting to isolate that. I don't think I can unless I have developer access and root the phone. I will not be doing this knowing that there is a manufacturer/carrier defect on my device and they are on the chain for it's repair at the moment. Software, phones firmware agree that it is a CDMA + LTE/EvDO device but SIM has to be removed, phone booted without, TURN OFF, reseat SIM and power on to fix boot loop after charging for a while every day so far. Verizon why am I troubleshooting an issue that your techs should have figured out before pushing a manufacture update? I am paying for Verizon service because it's better than Sprint and AT&T but not cheaper in my area! Where is the Verizon rep with assistance?

Could be something with the new verizon location service that was introduced with the update.  So far, I haven't heard exactly what it does, but if it is polling the towers for your location, that could be the issue.  Personally, I haven't had any problems since the update, if it wasn't for the extra signal bar, I probably wouldn't even notice.  However, the battery over heating is a common problem with the Rezound and, from what I hear, Verizon is being pretty good about replacing batteries for anyone having an issue.

  • Macbook Pro has short battery life and runs hotter after firmware update

    I installed the macbook pro EFI firmware update yesterday and now my MBP runs hotter and the fan starts running earlier than it has ever done before. Also, my battery lasts 51 minutes from a full charge whereas, before the update, it lasted 2 hours (using the same programs and display settings).
    Has anybody else seen this problem?
    Please tell me I'm not alone with seeing this. I am hoping that there is a solution and it's better than 'buy a new battery'. The fact that my box now runs hotter with the fan on more constantly would not be solved by a new battery I think.

    Also had the problem of MBP running much hotter after most recent Firmware update.
    My fans have been running at 6k RPM constantly, and processor Temps have been running at 70-88°.
    Following the advice in this topic, I checked the Activity Monitor, which told me both my account and my son's account (which was running but had no actual applications running) had separate Airport processes going nuts – each at approx 80-95%!
    Switching off airport and logging out of my son's account almost immediately started to cool the processors, and the fans began to slow down. Switching Airport back on doesn't seem to heat things up again, but if I start to crunch numbers, it all happens over again...
    So who knows why the firmware update is making these processes freak out.... weird.

  • Here we go again. 5.0.1 has terrible battery life AND loses 3G connection now!

    I have another friend with the same issue, battery life is horrible still, dropping 10% in minutes. The phone also loses 3G connection, which I'm guessing is the problem because the radio is working overtime to reconnect.
    What the **** is going on.

    It's a conspiracy against you

  • Short Battery Life and Very Slow Data on 4S

    Short Battery Life and Very Slow Data on 4S,
    anyone else noticing the slow speed of data on this phone?

    Yes, I measure my slow data on Sprint in kpbs, not Mpbs. Like standard is download maybe 250kpbs, upload 100kpbs (that's 0.25 Mbps and 0.1 Mbps). On the same tower my buddy who has an AT&T iPhone 4 shows 2.5Mbps download and 1.5Mbps upload (that's 2500kbps and 1500kpbs), a LOT faster. Sprint has not been much help.

  • New update fixes heat & battery life???

    Seems to for me....the airport/security upgrade that is. My MBP def seems to have better battery life and seems to run a little cooler. Strange, but i'm not complaining.

    Updates do not decrease battery life.
    Why do you believe such a silly thing?

  • When I got a new iPhone5, I experienced short battery life, and system sofware issues were not the cause. The camera also takes a blury picture regardless of lighting and I have the black one. Has anyone else experienced similar problems?

    What makes you so sure it isn't software?
    The camera can be focused by take the point of focus on the touch screen.
    If it is new as you said, it should be under warranty. Make a Genius Bar appointment or contact Apple with a repair request.

    Your battery has reached the end of its life. If you have a MacBook with the removable battery you can get a new third party battery fairly cheap on eBay.

  • If macbook retina gets too hot, can it shorten battery life span ?

    hey guys, when I'm gaming on Windows in bootcamp, I'm getting temps upwards of 176 degrees F. Is this normal ? Can it damage the battery life span ? For instance, if battery reads 8 hours on full charge but now it reads 7 hours with same processes running each time

    No, that will lenghten its life. Using the MacBook on the battery is what shortens its life.
    If you're running Lion your battery will run down much faster than on Snow Leopard. Lion runs in 64 bit all the time where Snow Leopard only ran in 64 bit as needed.

  • Anyone experiencing diminished battery life and delayed response times with iOS 5 on iPad 1?

    Since installing iOS 5 on my iTouch and iPad, the battery life of both devices has been terrible! Before I could get 1-1/2 or more days use, now I'm down to hours without using the device. . .and I've turned off all of the locations services except, find my phone. Next, I'm going to try turning off the auto time zone setting.
    I've also noticed diminished response on my iPad when opening Settings, Notes, etc. --like 10+ second delay before anything happens. I'm really considering restoring my devices back to the older OS.

    Downgrading the iOS is not supported. My iPad is a bit slower that it used to be, but I havn't noticed any change in battery life.
    In terms of response times you could try closing all your apps completely and then do a reset and if that improves things. To close all apps : from the home screen (i.e.not with any app 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of each app to close them, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
    To reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.
    For battery life have you done a charge cycle since you updated :
    For proper reporting of the battery’s state of charge, be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).

  • Poor battery life and WiFi connectivity on iPhone 5s

    I have bought a new iPhone 5s 16GB running iOS 8.1.2 3 days ago. The device that I have got has a poor battery life and WiFi connectivity. I have tried lots of methods given on the internet like turned off the auto-brightness, reset the phone to default settings.
    Then contacted the Apple Care for battery issue. They asked for the diagnostics to check the problem. They said its happening because of the crash of inbuilt app Springboard asked me to try "Set up as new iPhone". Even after doing all these, I am still getting battery not more than 4 hours.
    This is not expected from Apple. Such an awful experience on my first iPhone buying.

  • When downloading updates for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed.

    When downloading updated for Quicktime 7 and Itunes 10 I keep getting an error saying that files shared by these updates has an invalid signature and that the downloaded has been removed. If I don't get that message I get a message saying that the download was unsuccesful and that in order to download I need to go to tools and then select dowload only. Please help I really want to update my iphone!

    Thanks for helping out, but I already tried these steps.
    I even tried this on a iMac with similar results. The only difference was that the errorcode was called 2001 instead of 21.
    Today I took the phone to www.iphoneambulancen.dk. A guy (in Aarhus, Denmark) that specializes in iPhone repairs. I figured, that given his occupation he'd seen most errorcdes. Two hours later, he called me back, and told me that he had replaced the battery.
    So, it turns out that a broken battery can cause this behaviour.
    But thanks again

  • 3g iPod battery life and hard drive head...

    Hi all!
    I have a 3G 20GB iPod, and sometimes the battery drains itself out even with a brand new battery and the iPod being shut off.
    I can barely get 4-5 hours of playing time, no backlight, equaliser, and no songs skipping.
    I found out that you can hear the head of the hard disk moving even when the iPod is turned off. One of my relative has a 3G 15GB iPod and she's experiencing the exact same problem of battery life, and her iPod's hard drive make's the exact same noise. And she also has a brand new battery.
    So can you listen to your iPod, (even between times when the iPod has stored the data to it's RAM the head of the hard drive is still making some kind of movement) and tell me what you think.
    I've tried to install all previous versions of iPod software to no avail.
    For now I have completely erased the drive with "zero all" along with a surface test by Tech Tool Pro, and it seems to have made a difference.
    Time will tell, post your observations and I will keep you posted.

    The largest detractors for battery life are the obvious ones like backlight usage, anything that makes the HDD seek (FFW, skip track, etc...) using EQ, and volume. There are many other areas but most are pretty minor. Alot of it actually depends on the chip that regulates energy to the player. Supposedly we will be seeing new chips that double or triple battery life on these mp3 players in the near future but we shall see.
    Hard disk is by far the biggest user, backlight uses some (but you wouldn't have the backlight on, and it's not good for the life of the EL panel either). EQ seems to have issues on some players where it uses far too much power in my opinion, specifically the Smart Volume function. I hope Creative can address the power demands of this if possible. Creative managed to double the base battery life of the Touch with the changes they made in some of the hardware, so greater li'ves are definitely achievable.
    Rich_T: I've used your excellent test data as the start of a battery curve graph I'm putting together. I'm taking Creative's benchmark data and anything else I see to try and create curves for the players under different circumstances. I think once we have a base curve for one circumstance we can probably extrapolate it to all the other players, at least as a guess.
    If anyone at Creative has any battery life figures for different scenarios (which I would be amazed if they didn't) it would be very useful
