Short battery life!

Hello people, after having used my Touch pro 2's GPS function extensively one day on battery, I have realized that the battery's life has shortened by huge amounts of time. It lasts for less than 24 hours now, so I was wondering if I needed a new battery or is there something I can do to restore it back to the previous state. Thanks!

I don't think using the GPS should ruin your battery, just doesn't make sense! Are you sure you shut off the GPS after using it? Are you running any other programmes in the background? Did you flash a new ROM?
My battery started going down twice as fast after swapping to the new "official" Sense 2.5 ROM.

you can try a couple of things that may extend your battery life. try first turning off the auto speakerphone when the phone is face down. i just did this and i can tell a marked difference in just a couple of days. also search battery life reg edits. theres a ton out there here and on ppcgeeks that will definetly help. in general i noticed that when I use GPS the battery drain is pretty high. hope that helps

Using the GPS all day will def drain your battery much faster, especially if you're using aGPS and/or an app that also downloads data to compliment the location info (like google maps). The GPS radio isn't 2-way like the phone or 3G or wifi, but it's still a radio and will give a noticible hit on your batt life when used even moderately, let alone all day.
If you're going to be using GPS a lot, you might want to try different radio roms to see if any of them make a difference in the batt life for you, but I don't know that will make as much of a difference as it does for the phone reception, etc. I would also suggest evaluating various GPS apps, with an eye on relative battery drain

Well guys, thanks for the answers, but that still doesn't solve my problem because I don't use the GPS function often at all, but the battery still drains quickly. Also, there are no programs running in the background. There is however a data connection that is always on and the mail checks for mail every hour. But the thing is I don't want to change any settings to enhance battery life, If it worked fine with the same settings before, why wont it do the same now? Do I need a new battery? Thanks!

Ahhh sorry, I misunderstood, I thought you were just saying it drains faster while you use the GPS like that, not since you used it...I get it now.
That one day of heavy use shouldn't have killed your battery, take a look at THIS thread, others with the same issue/question have posted different things that have worked for them...you might want to give the steps in post #31 a try before thinking about buying a new batt.

You can install " battclock " and you can continuously see what the battery drain actually is during different functions.

Yes, great recommendation! (why didn't I think of that? lol)
And with battclock you can now see your CPU usage in real-time, which is probably one of the best coincidental indicators of battery drain (much more so than memory load, in my opinion)

Hi Dimitri,
I experienced the same problem where my battery life suddenly "shifted" from 48 hours to 12 hours on regular use..
I thought the problem was the battery and I replaced it, this did not help at all..
The only cause of this problem that I can think was loading the official HTC UK 6.5 ROM (1.86.401.0)..

This is exactly what I am experiencing. (This together with not being able to connect the device to PC)
Installed several 6.5 ROMs and suddenly the battery lasts only half a night.
My question is: When the battery is full, when you turn the device off (completely off, not in standby mode!) does the battery drain then?
As far as I see, the battery has only 50% left after a night rest while it is off. So, the only way to keep the battery full is to remove it from the device.
What are your experiences with this?

If you are truely turning it completely off, the battery should NOT drain at all. Have you tried a new battery? I bought a pair of batteries and an external charger on flEabay for like $12. The batteries are good as originals as far as I can tell.

Yes, I have two batteries, even an external charger.
Even when a battery is charged with the external charger, then put in the phone it drains the battery

hey guys can anyone link any of the forum topics to tweak battery life? the only things I have done is the general setting on the phone and the power management options with advance config are there more options and tweaks available?
thanks for all help!

Bright light...I'm also having BOTH of those problems...stock ATT rom. Within the past week my battery life has dropped exponentially, and when I went to sync last night, had not done so in a week or so, I get nothing...none of my PC's will recognize the phone as even being plugged in, let alone sync. I'm thinking maybe an ATT botched update?

So it seems I'm not alone.
Mine is a universal one, no brand whatsoever. I will try to reflash the original (6.1) stock ROM, including radio.
Have you flashed yours already?

@Bright.light @VirtualHomer:
I have the crap battery + no activesync issue.
I'm on the Josh's Black 1.7 ROM. I tried hard reseting, reflashing, going back to the stock ROM, but no improvement.
I have heard that removing the battery overnight is a possible fix for the USB issue (maybe for both?), but I haven't tried yet, will try tonight.
If anyone out there has any potential soultions here... would be great. Right now, I only get 1/2 a day (~6 hours) out of the battery & no hotsync at all (other than BT).
One thing I am pretty sure of: The bad battery life and the activesync issue came up around the same time. Wierd.
Cheers

You are right in assuming that battery life and connectivity issues came at the same time.
I was assuming this was because of a (bad?) flash, or maybe a bad ROM which changed something in a position that should not be changed and which is not restored by flashing another ROM.
A night without battery won't help, I think, because my device has been numerous times without any power and without any battery. However, I will try it again.
Could this be a faulty device? Or a design error?

@Bright.Light
I confirm that a night without the battery solved nothing. I have had my phone on for 5 hours now, taken 5 calls, none of them too long, checked email every 10 minutes (automagically) and I am down to 27% battery.
Also, I confirm that a replacement battery solves nothing, as I have also tried this.
I am planning on returning my device to an ATT store next week for a replacement... We'll see how it goes.
Cheers,
Matt

I'm in the same boat with mine. About two weeks ago the battery just started draining fast. Fast enough that it wouldn't make it to 4-5 hours without being charged. You could watch the battery meter drain. And what was weird was that there was no ROM change or anything that started this. Came out of the blue. Calling Spring tomorrow and getting a replacement is the best solution I can think of.

[CONCEPT] Bad Battery Life

Just recieved my 2400 MAH extended battery, I have had the device running now for 12 hours straight with all connectivity turned on (including syncing, wifi, data) and in that time I have also done some web browsing. The battery is still at 100%.
I know it is an extended battery but still, by now my standard battery would be at 50% roughly.
My concept is that the standard battery the phone comes with maybe faulty or have some problems?
Any thoughts or ideas?

It heavily depends on the ROM you're using... I've tested several Sense and non Sense ROMs and the variation of the battery could go from 1 to 3 days aprox. I'm actually using OpenDesire latest ROM and its easy to get 2 days of battery life with a normal use and 3G/Sync enabled all the time.
Obviously having a more powerfull battery also helps...

Well i've got an unrooted desire and using stock 2.2 rom. The battery life has been so bad, even when i turn syncing off.
I know its an extended battery but still why was the standard battery so bad

Hmm. Not sure. I don't have a bad battery life, but that sounds pretty awesome as far as battery life goes. You wouldn't happen to have a link to where you bought that from would ya? Would be interested in taking a look at it my self. Is it larger then the normal battery, or just higher capacity? I know many of the aftermarket batteries are a good deal larger then the stock ones.

I can't see how your battery could possibly show 100% after 12hrs usage
It's either bad battery stats, or the battery status indicator isn't scaled correctly for your battery.

Dave

it is probably because its voltage figure is still higher than that of a standard one.

Worried about battery life

I am a heavy texter with medium to low wifi usage. Sometimes I play games on my cell (Everlands) & last night I did some chatting.Usually battery last about a day but sometimes it goes down like after 16hrs which is quite low for what I have heard about this phone. Any way to identify the problem is ?
Maybe that is because I did not really charged uninterrupted on the first day due to constant loadshedding here in my city (about 1.5 hr gap in charging). I've heard Better battery stats is a good way of locating draining problems but I couldn't really understand it well enough to use it to my advantage.
Also I have set my brightness to lowest most of the time so thats quite surprising. Also net usage is mostly web browsing, no google maps or auto sync feature enabled as far as I know. Any tips about locating the problem ? Could hard reset possibly solve this issue ? Anyway my phone is less than 1 month old (3 weeks old) so should I consider taking it to service centre & getting battery replaced. Please help.

The battery is calibrating within 3 weeks if the phone is new (5-10 charge cycles) so the problem might not be a real one.
Are you on stock rom, stock kernel?
IF not, do you have kernel with overclock capabilities (titanium kernel, kiss kernel)?

The calibration thing sounds interesting. Everything is on stock. The phone is unrooted though I once thought of rooting it & rebooted the phone in recovery. How much does the battery last for u ? Right now battery has gone from 100 to 86% in 12hrs with somewhat lighter usage. Is this normal ?

I'm having 48% after 10 hours with screen on at 61% but it is like this because i plugged in to my computer last night to put something on the sdcard.
In general your informations are alright, that is a fairly good battery life. Remember that you have a smartphone with gpu and cpu, and it is normal to eat battery even if when you don't play with it because it makes stuff in the background.
The great battery life i got at 3 days with 50% screen on, wifi, calls, sms at 10-15% but not on stock, using CM9/Paranoid Android and tweaked kernel for better battery life .
In conclusion, don't worry about it. Your battery is fine!

If you really want better battery life try flashing a custom kernel like KISS or Titanium and undervolt your CPU.
I managed to undervolt mine alot (-300mV while idle) and battery life increased to almost 3-4days, which is really impressive compared to 1.5days it lasted before.

How could you undervolt that low? It doesn't freeze your phone? At what frequency did you undervolt this low?

Its usually 1-1.5 days for me,its always on eater wifi or mobile network.
And i text a lot.Gmail,Whatsapp etc.
Screen is mostly at 70-80%.
As far as i am considered thats good,a lot of phones these days cant even get to 24h.

It works perfectly stable with the following settings:
Clock VDD (mV)
'24576 700'
'61440 700'
'122880 700'
'184320 700'
'192000 700'
'245760 700'
'368640 700'
'768000 850'
'806400 850'
'1024000 950'
Took me about 2 days to find them.
Sadly you cant go any lower then 700mV, seems to be a kernel restriction.

In my last charge the battery ran for about 1 day 6hrs when it said low bat, which is fine for me. However few times it oddly discharged like in 18hrs. Maybe I played too much games & used a lot of wifi at that time.

"Battery calibration" is snake oil. Period.
Also, I have 2 stock One V's in the family, rooted but no custom ROMs. Both devices on occasion (once a day at least) appear to be in sleep mode but taking the phone into a completely dark room reveals the backlight is still on (albeit very dim).
This is the only thing I see that's keeping my stock ROM from outstanding battery life. Even as is it get good battery life, but I also double check periodically to make sure the screen really is off.

It's all over xda. However, here's a link:
https://plus.google.com/app/basic/stream/z13dgb0rksywh3muq222fzkqnwfgdbgrk04
It's from Dianne Hackborn, android developer for Google.
from here

Root your phone, put kernel titanium kiss, make it with 1.2GHz and smartassV2 cpu governor and than flash with full wipe myOneV 8.0 rom, put display brightness to automatic you will have stunning results.
P.S. make back ups to your data but do not restore it all from recovery

Hi, now that i have your attention!
I have cm7.2 democracy on my gio
I barely use it for wifi or gaming now because the battery is S**t.
I had 2.3.6 GB before and battery could take out 2 days on games and music. Now suddenly after switching to cm7.2 i need to charge it twice a day without using any app or game. just some texting like 10, 12.
I use ondemand governor and max freq is 806 min is 245
Also a couple of times i have seen that when my battery is at 30% and charge it then within 5-10 minutes it showed 100% charged. Unplug the charger.
Any suggestions or something on this? I really need an answer guys. Thanks

I can tell you that you can't charge your battery within 10 minutes.
Charge it at least 2 hours, 2.5.

No one has found a solution 'till now?I'll try to use ODIN and go back to stock version, maybe that will help. Has anyone had those battery problems before using a custom ROM?with stock my battery used to last 2 days with games and music etc, now I can only use it for 5 hours without any games or music or internet. It also charges from 0 to 100% in 30 minutes , maybe less. I'm still hoping someone found a solution for this problem because it is useless to have a phone without any battery.

Try to get a new battery because huge draining problem is not caused by roms it caused by battery damage.my battery runs on stock rom over the 10days without using anything but on cm9/10 roms it drains faster but still runs more than 3days for me.

so no one got it?
Thank God I am not the only one here
But guys, I have been using stock GB for an year. Its been only a week on cm7.2 democracy and nightly.
Both have same battery issues and non of this happened in stock
It's not the battery issue.its something else. I'm sure

Have you tried going back to stock version using ODIN?I think that is the ultimate solution before sending my phone to service(I still have warranty).

Try to "recalibrate" your battery; in cwm theres an option "wipe battery stats". some say its nonsense, some say it really helps; i would give it a try.
No idea if theres an option with stock roms, though.....

I'm calibrating now...Will post the result in a while. (Tomorrow i guess)

I still couldn't solve this..I flashed the stock firmware with ODIN and still no luck, I'm starting to think it is a hardware problem, maybe I will send the phone to service now that I have the stock firmware back. Has anyone found any solution?

Hey, i found this article
For the users who like to try out new ROMs very often or by default Android receives updates to Android very often. These updates re constantly pushed to the users to provide the better experience to the users. For those who flash their mobile handset with custom ROM they are advised to charge their handset to 100 % battery life and then proceed with the upgrade processor. That is advised because if you have 50 % of battery life and proceed with firmware update, the new custom ROM will consider 50 % battery life as the full battery stats and this will provide half the battery life then earlier as specified by your phone manufacturer. In those cases you need to go with the battery calibration to gain 100 % battery backup as specified by your provider. There is complete procedure on how you will calibrate your phone battery is mentioned by us and if you would like to make the process very much easier then you can make use of a specially designed application which calibrates your battery. (Battery Calibration)
Okay so i flashed a new custom rom with 100% battery but no luck on battery issue. Its still draining the same.
then i calibrated my battery with this app with my battery at 100% which of course is 50% as said by this article, the app said "Your battery has been calibrated by 6%". Don't know what that means.
ANY HELP? DEVELOPERS PLEASE GUYS!

Try to calibrate it too.It may fix it.

I have the same issue, I am using CM10.1 RC0 by Olddroid but I think my problem is the charger. For the last month I charged my Gio using the usb connection from PC. Now, if I use the charger the battery drains faster than charging with the usb connection method. I am gonna buy a 1500 mAh battery and hope to solve this problem.

Lineage OS battery drain

Hi!
I've been running Lineage OS for about a week now and I'm experiencing poor battery life. I get around 2 hours of screen-on-time and I'm not doing anything demanding other than browsing and social networking and I have the settings on Efficient in the power menu. I feel like stock was a good 50% better on battery life than LOS.
I also noticed that LineageOS System, Android OS and the Phone Idle processes eat up around 30% of the battery.
I didn't install any battery draining apps and I'm running the latest version of everything.
I tried reseting app preferences but it didn't help.
I also want to note that standby time is amazing. If I don't use the device the battery level stays the same while it's sleeping. When I wake it, it loses 2-3% immediately though. It seems that it only loses battery quickly when the screen is on.
Can someone please help? Is this normal battery life on LOS?

if you want more battery life you can use Greenify or something like that. It is stopping the background apps. This is a alternative way. Hope you find your solution

Ah ok have a good career w/ android.. bye

Hey.
I'm using the latest LineageOS same as you, on my LG G2 D802 32GB and having the same issue as you. If I leave my phone on table for a night, it usually drains 1 or 2%, but if I start using facebook or facebook messenger, or just browsing the system settigs, or just ANYTHING, the battery percentage suddenly starts to count down, like 1% every minute or so.
So i've tried stock LineageOS kernel and Lambda kernel aswell (most advanced, latest kernel for G2 atm), rooting and using Greenify, turning everything down to minimal, underclocking GPU and CPU frequencies, changing govenors, battery saving modes on, screenbrightness to minimal without adaptive, everything syncing off, bluetooth, gps, and wifi is usually off, but nothing really helped and it's been buggering me for a week. Compared to the Stock 4.4.2 or 5.0.2, the battery is half as good. Also, I've been reading posts and I've noticed that not everybody have this issue, because some people experience really good battery - or they just say that -, on the same phone modell. I've been thinking about reverting back to stock because of that, but I havent given custom roms like (crDroid or AICP, I'm torn between those two) a shot, but that not relevant to you because G3.
If I find a solution I'll let you know.

LineageOS doesn't have any battery draining bugs for me currently. Have you installed a custom kernel?

G3 D855 user here. Can confirm the same issue, with all nightlies I have used so far. Standby is OK, but it still drains faster than stock. When I use the phone though, that's when it begins to go down waaay too fast. One percent per minute or two tops, certainly at least 2x faster rate. Tried to solve it in many different ways, so far to no avail. Asked some people with D855 and lineage too and they had no issue. It's a mystery to me (btw I bought a new battery just recently)

Second that, same D855 with latest baseband 21C, i encounter same bizarre battery drain..

I'm glad I'm not alone then!
Same problem as everyone else.
Overnight lose only 1% per hour but using the phone it drains extremely quickly.
Look at this crazy battery history:
I've never had this issue on my other devices running CyanogenMod in the past.
Has anyone tracked this issue down to something in particular?

Phew, its not just me. Stock LOS nightlies, pick any... same issue as described by everyone above.
D855/32Gb etc and can not shake it. Wakelocks are all good, as meant to be, just screen on seems to destroy the battery. Have screen on adaptive brightness with around 50% brightness on slider in the first place.
Something is not quite right. Love every other aspect of LOS apart from the battery drainage.

I've got the issue too. I don'y know why but it starts to drain the battery quite fast during the usage of the phone. Any help will be appreciated.

I don't see an open bug unless anyone else has seen one:
https://jira.lineageos.org/browse/BUGBASH-167?jql=text ~ "G3"
https://jira.lineageos.org/browse/BUGBASH-17?jql=text ~ "D855"

There's also this bug:
https://jira.lineageos.org/browse/BUGBASH-364?jql=text ~ "battery"
which is similar to what happens to me, i.e. get to 30% and then suddenly shutdown.

I think this is the bug:
https://jira.lineageos.org/browse/REGRESSION-372

Clear caches!
I was having this issue, with Lineage OS as well as some others i tried based off CM. I would get better than stock battery life for a few weeks, then suddenly the battery would start draining in a few hours.
Booting to recovery and clearing all caches fixed this issue for me.

This is a hardware issue with the battery, not a software one. You need to replace your battery with an official one from a reputable source (careful, there are quite a lot of fakes around, so don't be tempted by saving a dollar).

This sounds like some app you're installing on your phone.

I'd generally think that, but I haven't installed any apps for weeks!

I had already tried this but no luck.
Could you please check your battery stats?
Does the percentage used equal the total of the individual apps?
In my case, it never does, e.g. 15% usage but only 3% used by apps.

Same for me - the numbers never add up. When this occours, I can watch the battery go from fully charged to 30% in an hour or two, but the battery usage meter doesn't show anything like that kind of usage.
I'd post a screenshot, but I've just taken my phone off charge and have no data as yet. I'll post one tonight - but since clearing the caches, mine is behaving at the moment, although I'm not getting the same all-day battery I was 6 weeks ago.

Same here
Also experiencing this issue on my 6P. Lineage OS system consumes the largest portion of my battery and I usually only get 1hr 50 minutes max of screen time. The phone also seems to die at minimum of 24 percent. Just shuts off. I no longer think this is a hardware issue either as other people seem to be experiencing this. (On a somewhat unrelated note, I also can't flash SuperSU in TWRP without it going into a LOS bootloop)
