ICS killing HTC Amaze Battery Life

[junkeeroo]

Hey All,

ICS has killed my Amaze's battery life. I can confirm this is not an isolated incident nor is it just my imagination, as my wife's Amaze is undergoing the same crappy battery life. I've also read another forum thread about the same problem with many people having their phones replaced by T-Mo. One guy is now on his 3rd Amaze. Phone probably doesn't last more than an 1-1.5 hours even with Ultimate Juice Defender set to extreme. An added bonus "update:" the phone gets very hot now.

Anyone know if Wind is doing anything about this? I think it's about time I root my phone.

Cheers.

I have my amaze from mobilicity with ics I haven't really noticed a battery drain I can leave it for 4 hours alone and not use 1% battery. Just the wifi hot spot kills 20% per 1 hour and half.

Hi and thanks for your reply.

And good to hear that you're not having issues.

Leaving my phone with display off is not the issue...it will last for hours. It's the usual culprit when the display is on where the battery drains.

Well when I use my amaze or iPhone 4s for tunein radio with a active cell connection I could loose 30-40% per 2-3 hours, and with active displays for my amaze 50% in 4 hours it was like that with gingerbread it, I have not seen a difference with ics. Since I have and 4s I just got a juice pack for it, and stream all day on it. but by the end of the day the juice pack is dead but my iPhone is still at 100%. Still haven't found a decent juice looking juice pack for my amaze yet.

Battery was totally good before ICS, and my phone didn't heat up after talking twenty minutes either. Gonna reset it.

This is a great reply I got from another.
Sorry, forgot to get poster's name to credit them:

1.) Faulty battery - Call HTC they will send you new one for free.

2.) Rogue App that always keeps the phone awake so find what it is and uninstall

3.) Sync always on? Wifi always on? Gps always on? Turn it off or manually toggle (Use android power bar widget)

4.) Juice defender takes up more battery than it saves. If you do step 3 you don't need it.

5.) Root/Custom Rom and Kernel (advanced user, google and learn how to do it. Not hard once you get it)

I get 3-4 hours onscreen time and don't charge sometimes for up to 2 days on this phone. But I have a custom rom and kernel.

Also when you upgrade it is recommended to wipe data (factory reset). Then wipe your dalvik cache and cache (need custom recovery), followed by the update. If you don't do this it might cause problems. It might not, it depends but better to be safe.

I don't have an amaze, I have a doubleshot but similar internals. What you are describing sounds like what my doubleshot (aka mytouch4g slide) was doing. That battery life was abysmal and the thing would run hot on phone calls and anything else. (Hot like 107 to 110 fahrenheit or more). What finally fixed it for me was to replace the battery and to make sure that all services (gps, wifi, and apps) are not running in the background when the phone was sleeping. (FWIW, Juice defender will use a lot of juice if you have an app that keeps relaunching itself after it is killed by juice defender, which then must kill it again and again). I bought an Anker battery that had a slightly larger mah capacity and it doesn't get hot and lasts at least all day.

Don't know if the battery is your problem, but t-mo/htc generally will swap one out or send you one. ( The anker battery I bought on ebay for under 8 dollars and had it in three days.) For me, I master reset the phone and then loaded apps back one at a time and watched what it did to find the apps draining in the background.

Hope that helps a little. Good luck, I know how frustrating that can be.

It's difficult to blame ICS when that may not be all you "got" during the update. Others can chime in but carriers may make "additions" that are included in the
OTA. Thus, a Wind update may not be same as others.

So you may want to look at running services and see if anything is amiss.

I have found that if you have the screen on, the battery will drain quickly. It is simply a big screen, and draws a lot of power (not to mention that you are probably running programs like games or music while the screen is on). However, I found that stock ICS also is bad for battery in general. I'm running the NRG rom, and using Juice Defender (paid version with custom settings). I can go through the day with about 20% loss, with just average use for checking emails, weather, etc. I actually get through the day at 15% loss by manually turning the mobile data on and off as needed, but I find JD much more convenient.

If my son gets hold of the phone and starts playing games, it goes down fast. But at least I only rarely need the extra batteries I carry in my pouch.

So I'd suggest a custom ROM and either keep the data modem off (unless actually in use) or use Juice Defender.

EDIT: I'm on US T-Mobile.

Ended up getting a new battery from HTC... Did some HTC app clearing thing i got from Playstore, as recommended by HTC CSR and things ran better.

Now have a Note 2 though... Way better, bigger battery... All day with moderate usage no problem.
