Hey guys, I am having a problem with my Amaze, more specifically, the battery is dying absolutely WAY to quickly. For example, yesterday morning, after unplugging my fully charged phone, I dropped it straight into my pocket, and maybe looked at it twice the entire day. When I pull it it at the end of the day, the battery is red, with 8% left. If I were to be using it, the battery would last about 30 minutes on a full charge, most likely. I've also noticed that the phone is really hot, even in my pocket. If it helps, I am on ICS and have been using it since it was leaked in April, however, this problem is new (about 2 days ago is when it first started), as I usually get about 8-10 hours with moderate usage. Can you guys please help me? Thanks!
Well if it just started happening recently, and you haven't made any changes, then the battery may just be going bad... If that's the case, you can call HTC and they will send you one free replacement.

could be just the battery.. but if you don't mind me asking - how long have you owned the device? I suggest you dl JuiceDefender from the playstore and see if that helps - Definitely helps my device get through the day with moderate use and one time charge every 1 1/4 a day but this could vary on owners usage. Also, check your settings to conserve battery life such as turning off wifi, gps, auto syncs on your fb, gmail etc. and adjust your brightness to the lowest if possible and OH... less widgets and windows > less power that the battery consumes. Hope that helps!

Like I said, this just started happening. I didn't just decide to leave all my wifi and GPS and Bluetooth on all day. Also, to answer your question, I've had it since the beginning of the year. I think it's just the battery. I'll call HTC and report back.
cool.. i'm hoping its just the battery.

Alright guys, looks like it solved itself. Interesting...
I usually only get 6-8 hours on my battery, and its been like that from the beginning. is there something wrong with my phone then?

Nope, battery life isn't that great with this phone, depending on how much you use your phone and what all you use it for you will get any where from 6-14 hrs + or - some. Also your Rom and kernel will make a difference..

Nice!... Glad to hear
This happens to me from time to time, and the phone is ALWAYS hot when this happens.
What I've come to discover that it's usually something that' activating the phone while asleep.
The phone is hot, because the processor is being used. That's why the battery is completely dead so quickly, something is pulling it out of deep sleep and causing it to run full bore. The key sign is the phone is hot.
I recommend you get an app that lets you see wakelocks, and what's keeping the phone awake etc (I use GSAM battery monitor) Whenever I notice my phone becoming hot for no apparent reason, I know for a FACT that my battery will be dead in a matter of hours. Lately it has been "Android System" that's the culprit, and I can't quite nail down what is doing it, but it's very random and not much of a problem because I do a reboot and things are back to normal.
First, try to reboot your phone. Get system tuner and see what processes are using the processor when the phone is hot (make sure you show ALL processes, even the default excluded ones). Check the wakelocks. Get battery monitor and check the mA usage (it keeps a running history). When my phone is running optimally, I have a mA drain of around 70-90mA when screen off/deep sleep, and it should maintain this type of drain... when my phone is becoming hot for no reason, I see numbers anywhere from 300-600mA drain for no apparent reason. A lot of the time there was an APP that was offending, so I would first check that. Like I said though lately it has been "Android System" and it's kind of hard to nail that down, but it's so random.
When my phone is cool to the touch most of the time, I know it's running optimally because it's achieving deep sleep. I've found a lot of it has to do with what you had running before you turn the screen off. A reboot ALWAYS fixes it for me. If you can't seem to nail down the offending app, do a full reset back to stock and you should notice that your phone runs very very cool when the screen is off and it's sleeping. I usually get anywhere from 24hrs-2 days of moderate use with the screen off governor set to conservative, and maximum clock for screen off ~600mHZ. I use interactive governor for screen on, but that's for responsiveness and you'll probably have better luck with ondemand for battery life. YOu can set these in System Tuner.
Just remember, if the phone is HOT, it's using energy. If it's hot, something, somewhere, is causing the processor to run at a high clock frequency. If the phone is HOT after being in your pocket/screen off for a good amount of time, something is definitely wrong/rogue app. The phone should never be hot returning from deep sleep. I bet if you check your default battery monitor (The android one) you'll notice that the bar for AWAKE is probably almost solid blue, something is preventing it from going into deep sleep. If I notice my phone is hot when I take it out of my pocket, I immediately know that something isn't right. This should NOT happen.

I'm just past my 9th day of using my Amaze 4G.... so far, if I turn off data and turn off autosync, my drain per hour goes below 1%/hour... so i could get >50 hour idle battery life + 4 hours screen usage
with data on and autosync off, maybe 2%/hour -> this translates to ~ 20hour idle battery life + 4 hour screen usage
with data on and autosync on, maybe 4%/hour -> 10 hour idle battery + 4 hour screen usage
I have only calendar widget on my home page, only Google Accounts on auto-sync (2 mail account, 1 contact, 1 calendar)....

what program do you use to measure battery drain? I use Battery Monitor Widget, but it's not giving me an accurate answer (lets say I had the phone on idle w/o data/sync... the available % is stable over 5 hours (~1% loss per hour), but the current usage says at least -100mAh)
for me, the idle battery drain (apps autosyncing/using data) is the problem
I see my device properly going to sleep (deep sleep is the majority of the usage, not too many wakelocks/processes.....)
with data off and sync off, idle battery usage goes to a minimum

I use battery monitor widget to measure drain.. as far as accuracy, I'm not sure? I don't know if it's EXACT but it seems to be a pretty good indicator of drain. When in deep sleep the phone usually measures anywhere from 70~mA-120mA. Usually it stays below 100. Before I changed the screen off governor / max freq (screen off) it was almost always 100+. Screen off governor is conservative with a max freq of ~600MHz.
I have no idea how exact it is, but when it's reporting ~300mA, my battery is definitely draining much faster.. and when it's reporting 500-900mA~ my battery is draining incredibly fast, so it at least seems to be a solid indicator of current usage.

On my previous phone (LG Optimus T / Optimus One/ P509, CM9 ICS ROM), Battery Monitor Widget reports more accurate readings (idle with data off= -2mA or -20mA<dont remember>, accurately representing that 1% of battery would last at least 2 hours)
Phone with the new kernel (KozmiK Ruby -0.5a) still goes battery drain crazy (even with Juice Defender installed now).... I hit 10%, then got fed up, turned off data... then the phone slowly sipped battery for the next 3 hours going down only 1%.... sigh
I think Facebook Messenger is the data hogger in my case, since I do use it often... will try a new ROM build without logging onto facebook messenger, see how it goes

What you said is true, at least for data on - autosync on. My battery last around 10 hours idle + 3.5 - 4 hours on screen usage. It seems that autosync eats a lot of battery. Will try to turn that monster off and see how much it will improve. I have bad habit to push refresh button on gmail/facebook widget, even with autosync on,
I used to get 14-16 hours. Now my battery won't last more than 6 hours. I gotta replace my Anker

Most recently I got 1 day and five hours with a fair amount of use by using faux 011 kernel and using CPU editor script to set it to battery saving profile. I'm at 45% right now with fairly heavy use after over 18 hours.
Battery life is totally under your control, it takes some work to get it where you want it.. but you also have the option of buying a bigger anker battery with external charger for $20 and carrying that spare battery, and simply not giving a damn.
Just saying, battery doesn't have to matter for a very small price and a little space to carry the spare battery in your pocket.

Hi all,
when I go to settings < battery, I see that the Android system uses a lot of my battery, 61%. Standby is 18% and screen is 10%.
When I tap on Android system I see some stats. CPU total is 11 minutes, keep awake is almost 24 hours. The battery lasted 3 days at this moment and I still have 10% left.
What is causing this huge drain of the Android system?
the same here..

If it lasted three days then android would definitely be on the top near 60
It's normal with the usage you told
If it bugs you, keep your wifi on always and it would stay real low

Oh, ok. Didn't know that. Thought that Phone Standby would be the highest.
I leave WiFi on at all times and still the usage of Android System is quite high.
What's interesting though is, that Android System keeps the phone awake longer than it's out of Deep Sleep...
I'm having this issue of my phone not sleeping when the phone is off. I checked kernel wakelocks and the number 1 culprit is Power Manager Service. Anybody have any idea what this is. A distant second is wlan_rx_wake but I'm not too worried about this.
The devs are working on it. If you aren't on the latest CM9 build then you should update.

I'm actually not on AOSP stuff. I'm on one of Neo's roms.
Edit: I just ran a test and for 34 minutes the phone slept for 33 of them. Even though the phone lost 4 percent of battery in that time. I see people saying they have crazy good battery drain rates (like .25%/hr). I thought i would get better life but I guess thats just the way it is.

that rate is based on usage. keeping apps from starting. keeping apps running in foreground all the time. lots of frozen unnecessary apps. screen brightness between 10-20%. betterbatterystats monitors wakelocks

When saying .25% per hour I was talking about during sleep but I get 3-4% during sleep. I am going to try and wipe everything and start from scratch. But if my phone is sleeping >90% of the time when the screen is off, there's not much I can do to improve battery drain during sleep no(app wise), and screen brightness won't help at this level cause it's when the screen is off?
have to watch for partial wakelocks or any wakelocks. apps automatically starting when not needed or still running will reduce your amount of deep sleep. use betterbatterystats to monitor usage while it's off
Hey guys so the title says It all really, over night I can lose up to 10% which isn't normal I know
If I charge my phone up and use it straight I'll get about 5.5 hours out of It ( screen on time ) but if I don't use it to intensively it'll be about 4.5 which doesn't make sense
Sometimes when I reboot the device it goes down by a few percent as well, anybody had this issue?

Are you using STAMINA mode?
That's strange. Do you have a lot of IM apps and widgets/apps that updates in the background? As you probably know by now, you shouldn't see more than 1-2% drop in battery in 7-8 hours if you don't touch it. I'm on GPe now that doesn't have the fancy battery saving features, and i'm getting very good battery life. It's currently at 70% after 10 hours on and 2 h 30 min screentime.
It's probably something that's going rouge in the background, but check your apps that updates automatically.

I lose up to 15% overnight
I have Line / Weather widget / Twitter / Facebook / and more

Nowp. Got Stamina mode on, with only 2 exceptions: email + weChat, and also see a 10% drop each night.
I assume the problem is that Wifi or Data connection do not get disabled in stamina mode. You expect them to be disabled, until a request comes from the programs for a "poll event", reactivated, task finished, and then disabled again. But from what i can tell, the connections stay live.
Have you try juice defender. I use it better then stamina. I only have home page and none live wall paper and I only get 1 to 1.1/2% loss all night from 100% to 99 or 98 in the morning

I have noticed this once or twice before, last culprit was google keyboard in about 8h overnight it was almost always awake (about 50%), almost 2h of cpu time, used near 400meg of data - this was in SlimRom
Last night I had 81% battery before I went to sleep at 10:00. I then put my Xperia Z Ultra in Stamina mode. At 6:05 (8 hours 5 minutes) after my battery dropped to 80%
Therefore I only lost 1% overnight which is excellent.
Damn. Thought i was getting decent battery life (currently at 1d 6h on, 5h 25m screentime), but the way you're going you might reach 7 hours screentime on one charge...
And the cp12 isn't currently available where I'm at. Bummer.

Those battery calibration apps are a complete farce IMHO, modern batteries don't have their own internal memory like the old ones did, the best calibration you can do is a full recycle.

Yep. Also had a out of sync battery. Fully loaded ( green light ), it still showed 97% on the meter. So i drained the battery down to 1%, charged up to 100%, and voila ... Battery indicated correctly 100%, and has been correct every time.

If you are in an area with very poor cellular reception and your cellular radios are on this can happen. It would help if you would post some screenshots of your battery usage in different scenarios; otherwise we can't help you too much
You could have a transistor leaking current or a short somewhere inside the device. Try a factory reset if you've exhausted all other options and if it persists contact Sony.
Hello.. Can someone who knows about battery draining give some help? I ve got this phone a week or so and I think the battery drains kinda fast. I'm not sure. I used to have Xiaomi Note 9s with a super battery. I m uploading a few screenshots . Is it drains fast?? Or all looks normal? Thanks in advance
That is normal battery life for this phone. In fact it looks pretty good.
Thanks for your reply
On my phone there is always Android System consuming a lot of battery, almost like Screen. I don't know if that's normal. On a REDMI 9 of a friend Android System is almost consuming nothing
@Primal.pr28 the cpu behaviour is setup to react to user action, rather than anticipate user action. If reacting to user actions is priority, then you want to react to the user action as quickly as possible (phone = smooth). This is not efficient. It means that even the smallest actions may require processing speeds greater than necessary. With better optimization you could get at least 25% more usage of your device at no cost of performance. Consider switching battery saver mode on by default forever as well, don't think you lose much performance.
Yesterday I used phone literally from 100-0%, and I noticed strange thing, the reading that it reported as consumed power by the screen was ~48% but it says something like 1300mAh. So obviously totally incorrect. If the battery is 4250mAh, then half of it should be around 2100mAh, not 1300.

It's not percent of the battery capacity that is displayed. It's percent of all things like hardware & software usage put together including system and apps.

Do you use your phone for more than 24h?? Xiaomi is showing only last 24h battery stats.
I'm having the same problem, 12.5.5.0, I heard 12.0.8.0 is more battery friendly?
Same here, insanely bad battery life with 12.5.5, dont understand why, android system is using more than 25%.

18% overnight !
12.5.5 is same as 12.5.3, most resources are consumed by screen, sometimes buggy Google app "Carrier services". Around 10% overnight battery consumption, phone lasts about 45-50 hours (light use, web browsing, work profile, emails, Whatsapp, constant synchronization of private and work apps on).
