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.
Hey please don't tear my head off, Ive been looking through all the threads that I can, but haven't really found an answer.
So I got my g2 and left it stock for a couple of days and the battery did pretty good, meaning I didn't have to charge it during the day. I then rooted and flashed cm 6.1.1 stable and the battery was terrible it would drop about 1% every 5 min or worse if I was playing a game or using maps etc.
I tried switching to pershoot's cm_2632.28 012211 and it was just as bad. I then tried reverting to a back up of stock and it is still bad, I also tried RC4 and one of the nightlies, same problem. I tried wiping the battery stats with the instructions on cm's wiki, still terrible.
It is really frustrating to me and I have been looking around and it seems a lot of people are having trouble with battery life. I don't really want to buy another battery, and have tried removing anything on my phone that could use battery (widgets, apps, etc.) I also think it's odd that Cell Standby takes up the most battery.
So really what I want to know is does anyone have an idea of something for me to try? A mistake I might have made? Tip? Or am I just crazy in expecting my battery to last the day on stock?
Any help would be appreciated thanks
A lot of people who ran the cm rom seemed to have this problem I don't and I assume it only happened after cm and still occuring I think somethings wrong with cm's kernal idk but it seems like it shorts out the battery because I ran a wrong kernal on my stockrom and had terrible battery life.
Sent from George2.0 (G2)
The battery truly might be a dud... The fact that your Cell Standby consumes most of the power is probably normal because you said you stripped your phone of widgets, apps, etc.
My gf has a Wildfire and her first battery couldn't last more than a couple hours, and she's a fairly light user. She switched out the battery and now it's fine, goes for a couple days now..
I am running cm 6.1.1 oc to 1.2 I do not have this issue. Try a new battery maybe?
Which kernel are you using? And with what settings?
Kernel is toxygene #1, screen brightness auto, gps off, bluetooth off, Wifi only when I need it, "wcdma only" so I don't get any edge drop-offs, overclocked to 1.2ghz-368mhz screen on, 245mhz screen off. My battery will last 9-12 hours of normal use, that's a few calls, some txting, facebook, mp3s in the car on the drive home from work, and an hour or two of XDA. I unplug at for work at 10am, I let it die and charge from 0 every day..
Google sync every hour, weather widget sync 4 hours, facebook widget every hour. Those are all my widgets.
You should really upgrade to CM7 now. Pretty stable, and my battery life is SO MUCH BETTER. If I use my phone heavily I will lose about 30~40% during the ENTIRE DAY lol. So my battery with moderate usage will easily last 12 hours. Before I had the exact same battery life as yours.
Also, I'm using the UV kernel from pershoot.
Sent from my T-Mobile G2 running Cyanogenmod.
I'm on Virtuous v0.9.0 and I routinely get 12-15 hours a day out of my phone. That's with brightness set full, WiFi running (and usually connected), Tweetdeck, gmail, gtalk, etc all running with constant updates, etc.
If I pull it off the charger at 7a, by 7p I'm typically still around 20%, depending on how much extra use I've done (sms, voice calls, etc)
Yes, the newer version of virtuous is great on battery life and doesn't even have to be oc. I just flashed back to cm today to get everything up to date (I'm ocd like that and have to have all my ROMs current) and I too am having the cell standby issue with 70% battery after 2 hrs and light use. Just flashed the newest pershoots and letting it fully charge before I clear batt stats... will report back.
Have setcpu set to lowest with screen off and oc 1.2-346mhz

synchronization
I am using Visionary 0.9.0 and I had lousy battery life too, and have now either turned off background synchronization or at least made it very infrequent for all my apps that use it (facebook, peep/twitter, HTC Sense, HTC Hub, News, Weather, etc. etc.)
This has made a very big difference!
The biggest difference of all came from turning off synch within the HTC Sense and HTC Hub apps. These were having trouble connecting to their servers, and were constantly tying up my 3G signal causing battery drain. This change alone has almost doubled my battery life.
I recommend you check what is using wifi/3G and how much before we assign blame to kernel or ROM.
Also, I can recommend GreenPower app which turns off connectivity automatically when it's not needed, greatly extending battery life. However after a long period of using this successfuly, I have turned it off as I started having trouble "waking" my 3G connection during the day. Hopefully future updates will help with that app.
I had the same problem with my first G2 and after complaining/convincing T-Mobile it was defective, they sent me a replacement and that problem never came up again.
Alright I feel stupid but I was charging my phone with my bluetooth charger (didn't even think about it) but now I'm using the stock charger and my battery is lasting way longer. Night and day difference. I don't exactly understand why this would make such a difference in technical terms but eitherway major facepalm.
when i first installed the latest release i had amazing battery life. Now im at 70% an hour an a half after i unplug it and it prpbably wobt last me another 5 hours. I dont think i have any apps draining the battery. Ive wiped battery stats. What's going on?
Sent from my PC36100 using XDA Premium App
If you used 30% in just over an hour, either you used it too much, or there is some app/process draining the battery. Download Spare Parts, go to Partial Wake Usage in the Battery History. See if anything stands out. If not, re-wipe everything and re-flash the rom. I'm running the same rom, and can go at least 3 days without charging.
battery usage history force closes spare parts...
Same here, it force closes when I look tap history. However I stopped using the changing photos lockscreen and my battery life seems to be improving.
World peace with no regard for human life.
standard wallpaper, and wallpaper lockscreen. I re-flashed the rom.
I had the same problem with an extended battery, only it would charge to 80%, then it power itself down and the battery would die. I took it to Sprint, they were awesome, the tech said that the modified scripting from the 3.0 Sense Roms is causing this problem on some phones, especially with extended batteries, rather flash my phone to stock, he gave me a differnt battery, wiped dalvik, said he did acouple things to it, and advised me to run a different ROM and see if that helps, preferrably a hybrid that the battery scripts have not been modified. I think alot of it was somewhat bs, but my phone holds a charge now, I am currently looking for a different rom...
It started out draining real fast, then it wouldnt charge after a few days
Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?
Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
