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.

[Q] Battery Drain - Yet another whining thread - CM7.2

Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!

it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.

Have you tried calibrating the battery?

Hey scilax can you please tell me how to. Calibrate the battery.
Me too get a smaller backup when 3g is used for some 3 to 4 hours.
Please tell about that calibrating
Sent from my Wildfire S using XDA

Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.

so, the battery drain is real...

I thought people were just exaggerating (i still have hope that i'm exaggerating) but man, i just got this phone and holy hell is the battery getting destroyed by "android os"
It won't even last a day with minimal/medium usage (some bluetooth and hotspot use here and there)
I'm coming from a galaxy s3 (which had better battery life).
I've tried installing a 5.1.1 rom but it seems to have no effect.
Has anyone figured out how to 'fix' this? Or can recommend a good rom (or kernel?) to get battery life representative of what i think a 3000 mah battery should be?
Thanks.

Greenify and the .97 OTA seems to provide decent battery life. Getting about 5 hours+ of SOT. Try using a separate app to see which apps are consuming the most battery and disable all the system apps you don't use.

I installed a barebones rom.
What concerns me is i had the same set up on my Galaxy S3 (5.1.1. lollipop with same apps), and the battery life on this zenfone has just been atrocious (leading me to believe 5.1.1 is not the problem, per se).
Am I wrong, did they not optimize this phone properly or something?

I do not have any issue with batery life. Mine last one day easy with medium to heavy use. Just do some charging cycles

I usually get a day with 4 to 6 hours SOT, without doing anything special to save battery

Do 3 drains to 1 % - you may find it stays longer during the lower 20% range so use a youtube film or sommat to blast it down,
then do a factory reset on the latest build.
Did this at the beginning when was only getting 10hrs max ugh !
Now easy 36hrs decent usage

I get a full days use (medium/heavy) with mine, not rooted not custom rom. I usually have about 20% left before it hits the charger. I have noticed small increases in battery life at every firmware update. I can't really complain, came from a Galaxy S5 and battery was about the same if not worst, but S5 had removeable battery. I've used a lot of smartphones and honestly, most will get your through the day and evening but that's about it, yeah, you might have some for the next day but most will through it on the charger by end of the night. My wife has the Iphone 4s and yeah, the battery lasts longer but the screen is almost half the size of mine, screen size makes a big dif.

Sub-par battery life?

So I am loving my new Pixel 2 XL, but i have noticed my battery life isn't nearly as what i see on the review forms. like with light usage only 2 hours of being unplugged, im at 77%. I came from my nexus 6 and transferred all my apps from it so it might be an app sucking my battery life? i don't know. any suqqestions would be good. I am rooted with magisk with the GMS Doze addon to try to help with this problem

It could be anything. At least with the root access, you can get many decent apps to track the apps that may be causing this. The battery on my 2 XL (stock) has been spectacular so far. I was a little bit worried that 8.1 may change that, but seems like it is even better now. For the first time in years, I am not worried about the battery at all. Even if I forget to charge overnight, I am OK going to work with about 40% of battery as I know I can get home with still something left in it. The only reason why I often check battery stats is because I still can't believe what is going on.

I am. Getting great battery life also rooted
Do a factory reset

I personally had worse results when I tried to tweak doze. Greenify also made things worse. My best results are leaving everything alone.

i think im gonna give it a few charge cycles before i do anything. i havent let this phone die yet, and i think the culprit might also be the life360 app.

I agree with this and I remember similar findings on the OG Pixel XL. I'd start by disabling the doze tweaking apps and see how it goes.

Check which app is draining the battery. My brother's unit for some reason had Google Play service draining 46% of the battery. After I flashed back to factory (without wiping) and enrolled the phone into beta program for the service. That worked out for him. (version 8.0 November patch)

My battery life has taken a significant hit since going to 8.1. No new apps (a few app updates through) but it is a noticeable difference from just a week ago. It's still impressive, but prior to 8.1 I would be at 70-75 at this point in the day with around 2 hours screen-on time, currently at 60% with only 1.5 hours screen-on time. I just got super spoiled for about a month or so with absolutely incredible battery life. Now, I have to live with "just" very good battery life.
First-world problems.

That's my experience as well. I haven't done anything to tweak my phone to try and get better battery life. I'm 100% stock. No unlocked bootloader. No root. Just out of the box. I'm getting 7-9 hours SOT over 24-32 hours depending on what I'm doing.

What I have noticed with 8.0 it use to drain a lot slower the first 30 to 40%, then it will drain faster, in 8.1 it is more consistent, I still average 7 to 8% SOT per hour and .3% an hour when screen is off. The phone still last 2 days with 7 to 8 hours SOT and I will be at around 25 to 20% still available. I had the phone since Oct. 20th and based on Accubattery I have charged it only 25 times in total

Remember that they fixed how battery life is calculated with the update. Also, you can looks under Background check under developer settings to stop specific apps from running in the background

That's some heavy battery drain, mine wasn't that bad, but close. If you spend most of your day somewhere with a weak mobile signal, try switching off "Mobile data always active" from Developer options. My office has very bad signal, and by switching off that setting, my battery improved a little bit. Nothing major, but it was noticeable.

Mine has changed noticeably, though not anything enough for me to be concerned in my daily use. Still getting 7 hrs SOT, just less stand-by time.

I rooted mine for like 2 weeks. I ended up relocking the bootloader and unrooting it. It just runs better that way.

This was me leaving it screen off unplugged for half the night and I can tell you right away the walelocks don't look right but I can't figure out what. https://imgur.com/a/SPIdL

I'm getting 7 hrs of SOT consistently. Not even close to sub par for me. That's heavy use as well.

I've noticed that many times people with poor battery life transferred everything from another phone. It seems like a crap shoot compared to starting fresh. Pre and post 8.1 I'm getting 6 to 7 hrs sot using around 55% brightness and mostly lte.

Seems like a lot of people are experiencing battery drain from Google Play services 11.9.51 (including myself).
Sent from my Pixel 2 XL using Tapatalk

So i factory resetted and reinstalled all my apps and stuff and still not getting good battery life. in 30 minutes from a full charge i was down to like 85% and that was just from listening to music
i cant tell what is causing it besides probably Google Play Services, so i enabled Doze on it via magisk, and still nothing. i highly doubt it's a defective battery

[A520F] Battery problems

Hi guys!
I have a serious problem with a used A5 (2017) I got from some friends. The battery life is abysmal. I already changed the battery and it didn't change anything.
It is running on Android 8 Oreo. The most serious problem, I think, is that the phone even discharges when it's powered off. I tried using the latest hadesrom, but it didn't changed a thing. Lifetime is around 12hours, doesn't matter if I run some apps or just let it lie around in standby. I tried factory rests and some battery saving apps... nothing works. Is there any way to get better battery life? Thanks in advance!

You could try the naptime app. But I don't think my battery life is any better than yours.

The a5 2017 has a famously good battery life.
I am not a heavy user - make and get few calls and mainly use it for receiving emails and a few texts plus a bit of web browsing.
Occasionally listening to podcasts.
3 days battery life is easy for me - reckon I could get 5 days if I just left it sitting quietly.
If it's going flat quickly even when switched off, it sounds like a fault somewhere.
Don't know what else to tell you.

I never tried letting it sit, but if I just left mine alone it would last for days too. But if I am gaming on it, it will go down to around 50 percent at noon.

wow - 3 days life battery!! I can hardly get to 2 days, without heavy us - but I would never try to change the battery -> sounds too complicated

One thing that is worth looking at is the Always on Display (AOD).
I found it sucks a lot of power despite the claims that it 'doesnt use much'. It seemed to use around 1% an hour - I guess thats around a quarter of your battery in a day. So unless you find it useful either turn it off - or set it on a schedule for when you actually want it to be on.
Battery life is always sujective and depends on what your phone is doing - gaming will burn through a battery like nothing else.
The OP said the battery drains even when the phone is switched off - That sounds like a hardware fault. The battery will gradually drop when switched off - but it should take months for a healthy battery to drop much if the phone is switched off.

1 percent an hour doesn't matter to me lol. I am a heavy user so I charge every day anyway.
