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.
Seems it's normal for Android devices to have poor battery life. So us having poor battery life on our Kaisers is probably due to Android and not the porting of Android to Kaiser.

buddy of mine has htc hero the phone is awesome if I were on sprint I would buy one, but I have att. anyways his batery life is terrible thats his only complaint
Yes same here, a colleague at work has a Hero, gets a day's use out of it tops, another colleague has flahsed his with 2.1 and says its a lot better, plus he can underclock ther cpu when in 'sleep' mode to save more power, nice.
How is the app called that can underclock in sleepmode ?
thx in advance
My colleague isn't in today, so can't ask him, but a quick google search suggested an app called 'SetCPU' this you can set max and min frequencies at, not free I don't think, but .99p not bad
Actually the poor battery life is a combination of android's power management and the result of us hacking it into hardware it wasn't designed for, however the point is still valid, and is partially due to the differences in the OS itself, which, being linux underneath, has a lot of stuff ticking away unseen.
Best practice, from my experience, is to just plug it into the charger at night, and use it wisely, putting it to sleep when not in use, killing tasks, and not using high drain functions unless needed.
Yea the battery life is dreadful on the android even whilst running on NAND thingy. Before I went sleep it was 81%, when I woke up (i only had a 7hour sleep) it was 65% :|
errrr, 81% to 65% drop in battery really isn't that bad, honestly, when you sleep, your kaiser does not, there are always a few tasks running.
However I usually put my kaiser on charge while I sleep, and I feel it's a good habit to get into with android....

I also do that sometimes, although I have read many places that charging Li-ion batteries more than they need can lead to shorter battery life. I know the batteries internal circuitry cuts the power off at 100% and recharges again when the batterys discharged a bit but from what I've read the best way to do it is to only charge when your battery is discharged a significant amount. I know they're not supposed to have that memory effect, but so many places with different information and I just cant make out which is right and which isn't. Makes me nervous when I'm unsure about small things like this...
Have heard this also, but never had any issues so far, however everything has a limited life, one day my battery or my kaiser will die, i'd prefer it to be my battery
Ah I think I might just switch back to WM6.5 < my battery lasted for so long even when i used it lots. Though once android has a better battery life, I will come back to it! Lol

I've always read that's your Li-batteries are best when fully charged all the time (if possible). I never had any battery problems in life.
Could someone please develop a good app that would enable the battery to be drained as much as possible and to charge slower so we could all properly calibrate our batteries?
Do we really need this since it's a Li-ion battery? I know Ni-Mh and Ni-Cad has memory effect, but not on the Li-Ion battery.
I was just wondering the same thing today....simply because there seems to be several different methods to do it. Some say charge 8 hours, turn off, charge and hour, unplug, turn on charge 10 minutes. Then other methods say to do something different....be nice to have an app to walk you through different methods so you know step by step your doing it right
I calibrated mine last night and I'm going to get about 18 hours if not more from it....before yesterday I was getting 9.
The ONLY other different I did was make some profiles on CPU but I cant imagine it would make that much of a difference. I bet its a mix of both

That is to funny I was just saying to my wife the other day that I should make one of these programs seeing that there are none already. I hate having to manually kill my battery every night before I charge it again.
Is it needed? It depends on your school of thought, some say yes, some say no. All I know is that on the few devices I have had in the past, if I constantly plug them in to "top them off" then the battery never ends up lasting very long after a few months of doing that. So I am a believer in killing the battery before charging on devices like these.
So the bottom line is if there is a desire for this, I may try to put an app together for it, as I know myself I am interested I just didn't think many others would be.
All the battery calibration tools, are basically deleting the file... right?
Is it that hard to boot into recovery and wipe battery stats?

I think the second part has to do with hardware. The phones hardware just doesn't have trickle charge implemented and instead lets it drop back down to 90% then starts charging it again.
As for the second part, it came on our phones, even has a default widget. 4G

Um... actually that is (by most accounts) bad for Li-Ion. You want to AVOID completely draining them. All of this stuff is more art than science, but I have way more often heard that completely draining LI batteries is bad. What kills them is the number of cycles they have been through (like -25 +25, -25 +25, -50 +50 would be a full cycle).
You do however want to give them a full up down cycle once in a while (maybe every 1-3 months) for calibration.
Then again, as I said, it is more art than science, and I have heard your method as being better, but the not draining argument seems to be the vast majority.
I'll try to do a little look-see and update this or repost if I find any stronger evidence.
the thing about my phone and battery that ALWAYS baffled me was i would plug it in at night be it at 10% or 22 i would leave plugged in while slept i would wake up unplug and look at battery percentage and it would be like 95.....no other phone has even unplugged and dropped 5 percent by doing nothing????
turn your brightness to 100% and change it so that it never turns off; use wifi tether and play a 720p movie at the same time; oc your kernel to it's highest stable frequency. it'll drain pretty quickly.
I know I might get flamed for this....
Apple suggests, with their laptops, to once a month or so, run the battery completely down. Then let the battery cool down for a little bit. Then give it a full, uninterrupted, overnight charge. I forget if they said to repeat this a second time, then you're good.
This is all from memory of me reading this a couple years ago or so, so our might not be verbatim. Their laptops use lithium ion technology...
(and they used to blow up and melt down too!) Lol!

That's because the phone stops charging when it reaches 100%, and runs off of battery probably until it reaches in the low 90s, then charges again. You won't ever notice this because the light will always be green. However, you'll notice that unplugging it a few moments after it turns green, the battery will stay anywhere from 100%-98% for a while. At least on my phone it does.
Is there any way to make this program "auto run" during sleep so it can do everything it needs to do during the night charge (similar to quickpull for blackberry)

I am by no means an expert so if you find any reliable info on this and can link us to read, I would love to learn more. All I know is that it is commonly said to drain rechargeable batteries and that I have seen that topping them off very often does lead to battery life degradation.

There is no need to fully drain the battery. Its purpose in calibration is to configure the software that is correlating voltage to percentage charged. That's all. Regarding the old Apple advice, that is doing the same thing. It will not affect the hardware.
Now, what WILL affect the hardware is charging itself. Every charge/discharge cycle will reduce the total capacity of the battery. This is why the EVO will not cycle on it's own until 10% discharged. It's improving the overall battery life by that restriction.
In short, you will save money overall by getting a higher capacity battery that you don't force to charge too often. Draining your battery does nothing but give you peace of mind and it only really needs recalibrating when it's total capacity has been reduced which isn't often. 3-6 months.

Btw - what are the charging calibrations people are using? Are you seeing one working better than another?
Im a noob, so take what I say worth a grain of salt but yesterday I did the standard method where you fully charge...turn off...plug back in until led changes green and do it a few times.
I went from 9 hours to 17 hours with no other changes except a few profiles in setCPU.
I did this just last night so my results are fresh.

A few SetCPU profiles is all it takes to see a dramatic increase in battery life, especially while screen off. If you disable it I bet whatever gain you think was from 'calibrating' it disappears.
When I got my one x roughly two weeks ago, battery life wasn't really that good. 8 hours max with a couple of hours of screen time. But I always calibrate my battery. When I got it I charged it for 8 hours then drained it then did the same thing for a whole week just using the phone till the battery runs out and then charge it for 5 hours... Now battery life is very good, EASILY last me through a whole day with moderate to heavy usage. Lots of tapatalk 2, browsing, messaging and emails. I'm also running ARHD rom so that also help but nonetheless battery calibration is important so do it people
Never calibrated or whatever, have excellent (for me) battery life.
I thought we got over this myth.....
OP, do you have some supporting evidence, or even logic, that shows that doing exactly what you shouldn't do with a li-po battery has a positive effect?. Have you A /B tested it against another handset where you treated the li-po battery as recommended? I.E, avoiding fully discharging it and preferably charge from around 50%.
I get up to 4 hours screen time and 4-5 days standby having treated the battery this way with just a handful of total discharges (obviously it not always possible to avoid)

Do I have evidence? No I didn't capture any screentshots or anything. This is from my personal experience I'm not here to prove to you anything, just sharing how my battery life is improving cause of battery calibration. My phone no longer display for example 25% then soon as I use it jumps to 19% like before. It decreases gradually and I get excellent battery life. Same thing with my I pad when is discharge it completely then recharge it, I see better battery life and better battery % display accuracy.

Li - po batteries do improve with the first few charge cycles but this has nothing to do with the fact you have run it flat. Doing so regularly will shorten the life of the battery. You stated that it had a positive effect but you have no comparison and it flys in the face of the laws of physics and chemistry. The point of my post was to make it clear to anyone who doesn't know better that it's bs and will be detrimental to battery life.
Though LiPo batteries don't like to be overly discharged, I'd stop short of saying that this is detrimental to your battery. LiPo batteries shouldn't be left at low voltage (dead) for long periods of time, but discharging it entirely and then recharging it is well within the designed specs of the battery. It's more the fact that they lose charge over time, and therefore leaving them dead which is considered their minimum safe voltage, will then allow them to drain further themselves over time to a point where it's detrimental. I suppose, though, a battery drained to 0% every single time is more likely to have a shorter life than a battery discharged only to 20% before recharging.
The Android system does calibrate the battery life, which is more of what you'd be doing, but you aren't going to get more battery life out of a battery by discharging it entirely, then charging it fully, it just doesn't work like that. LiPo batteries don't have issues with memory or needing to be discharged or charged to a certain point for optimum performance.
I 100% attribute bad battery life when you first get a phone to simply being you pulling it out and turning it on more than you normally would. It's nearly impossible, and damn near subconscious, but when you get a new toy, you're obviously going to pull it out to look at it, play with it, load every different app it has, etc, as well as doing the same when you show it to people. I think even if you think you didn't play with it a lot when you first got it, you likely still do. But that's just my opinion.

The dtremental effect will be minute, accepted, but there is certainly nothing to gain. That's what I wanted to make clear.
There is a lot of guesses portrayed as fact on here these days, as well as conclusions drawn from dubious experience with no control or comparisons. Just trying to combat this misinformation.

I know what you mean. I usually get yelled out when I try to do that and help, haha.

Li - po batteries do improve with the first few charge cycles but this has nothing to do with the fact you have run it flat. Doing so regularly will shorten the life of the battery. You stated that it had a positive effect but you have no comparison and it flys in the face of the laws of physics and chemistry. The point of my post was to make it clear to anyone who doesn't know better that it's bs and will be detrimental to battery life.

It flys in the face of the laws of physics??!!!??? What the hell are you talking about? I'm talking about my battery life getting better and better cause of draining it and recharging it not the gravity of the moon or Einstein theories, relax.

Yep, I just don't care if the truth means a fan of cereal box science gets their knickers in a twist. More than half of what gets posted now is erroneous guess work, assumptive, misleading noise that serves no purpose other than to dilute the factual helpful discussion.
I've never been much good at biting my lip.

That's fascinating..... I wonder where that battery calibration thing started in the first place, I guess someone made that up just to mess with people right?

For batteries that needed calibration? And as I said, a lot of people confuse calibrating the battery meter in the OS with calibrating the battery itself.

To all of you who say that using up your battery shortens it's life, I have just one thing to say: the phone will never let you fully discharge the battery. Approx. 3.5V at which the phone turns off is far from the voltage of fully discharging (and potentially damaging) the battery.

As I said, this has nothing to do with calibrating the battery, and everything to do with calibrating the battery meter in the OS, which, by the way, will never be off by HOURS, maybe by a couple of minutes. This only needs to be done once every however many cycles, that site says 30, but I wouldn't even bother doing it more than once every couple of months at the most as you likely won't see any real gain from doing so, and it IS theoretically bad to overly discharge your phone. Doing it once in a while won't damage anything, but doing it every cycle, or every day for a week or anything like that is excessive, unnecessary, and, as farnsbarns mentioned, can wear on your battery.
Battery meter calibration has been discussed on this message board countless times, and every time it's proven to be nearly pointless in real tests.
Edit: This is not to mention that I think a lot of batteries/phones have charging circuits built into them that allows them to properly check the battery level itself, meaning calibration of the OS isn't necessary. I could be wrong on this, but I'm pretty sure I've read about this before.

Nothing to do with battery calibration? Have you read the article? If you want accurates readings, you want your battery life to improve, you probably want to calibrate your battery. I've had the one x for almost two weeks and my phone doesn't jump from 50% to 42% randomly anymore cause I've calibrated the battery. If you want more reading : http://www.themobileindian.com/news/5547_How-to-calibrate-smartphone-battery
No one here said that it is something you need to do everyday, but when you get your phone I suggest doing it. Then once it's calibrated do it once a week or every other week.

they do have charging circuits I just read it, still you want accurate readings. Even my iPad sometimes displays wrong battery percentage when I don't let it discharge. Sometimes I charge it when it's at like 28% for example, let it fully charge but then it drains weirdly.

You are failing to listen to what I'm saying. I've read the article, and many others like it. There is no such thing as calibrating Lithium batteries, and it's a common misconception, so I have full faith that you can find countless web pages telling you you can. It comes from the old mindset of batteries that did need certain charge cycles (full discharge, full charge, etc) to maintain life.
Again, the only thing you calibrate when you run the battery all the way down is the OS's battery meter. Android shuts itself down automatically when battery voltage hits a level that is considered empty or dead, regardless of what the battery meter says, so that calibration gives you no more life out of your battery at all.
However, I think we all run down our phones to the point where they auto shutdown more than frequently enough to consider the battery meter calibrated very close at any given time. Battery meter calibration is more an issue on systems that stay plugged in frequently and don't often get discharged, this is usually with laptops used as a desktop replacement, not phones.
We aren't trying to be mean or anything, just trying to squash the continued misconception that calibrating the battery is possible or has any effect.
I have been searching as to what is the proper way to cycle charge so I can get the best battery life after installing new kernel and ROM.
However I seem to find different answers
One to drain in completely others say don't?
What do I do?

I wouldn't consider the manufacturer's suggested charging cycles to be "random anecdotes" even if they're not published in a peer reviewed journal.
"Completely draining" should not be practiced on a regular basis with lithium ion. You can't (or shouldn't be able to) reach an actual complete drain before the phone shuts down. If you could (or ever do) the battery would become useless to you as there is a point of low discharge where lithium ions can no longer be charged by a standard charger.
And while most of the time the shut down of the phone and the subsequent charger connection happens before this point - there have been plenty of people who have let their phones go till they shut down then go to charge their battery only to find it will no longer charge.
So every time there is a drain of your battery to the point your phone shuts off you get real close to that point where you will no longer be able to charge that battery (unless your one of those techno chemist electrical engineer types with all the appropriate tools and materials handy).

And i know i've read somewhere about someone suggesting that people go through this arduous process of draining the battery to a point, charging it fully, draining it completely, and charging it fully again (or something crazy like that... i don't remember exactly) to make the phone detect the full capacity of the battery and avoid any "memory effect", and i believe that whole idea was even shot down by someone at Google who works on the Android OS as being a complete crock.
I really don't think there is any PROCESS that can be done to give you the optimal battery life, aside from what can be done to prevent apps from draining the battery constantly. Some people recommend having a fully charged battery, or having the phone plugged in when you wipe the phone and install a new ROM... i've rarely done that. I've even wiped and installed roms at like 40% battery life... sometimes a bit lower. But in my experience, battery life has more to do with the ROM being used than what you did to try to MAKE the battery life better.
Running a touchwiz-modded ROM like DrewGaren's Serenity and stuff, i'd generally be lucky to get a full day of battery life seemingly no matter how much or how little i used the phone. I'm not what i'd consider a heavy user.... haven't really used my phone much all day today, though it did spend a good portion of the day on the charger. But i'm running the latest build of Task & Ktoonsez AOKP ROM, and it's been on battery for 9.75 hours and is still at 85%... but that's only with 20 minutes of screen time.
Anyway.... all i can say is from my own personal experience, but i don't think there is really any definitive process one can follow to improve battery life beyond what the software itself will do anyway.
Whether or not it has any effect on actual battery performance i would say that running a 'full' cycle or two of drain and charge for android to learn the battery capacity. Probably doesn't have much affect on a stock battery but when i purchased my 4400mah battery it took a few cycles to get an accurate reading from the charge meter. It would drain down to the warning in what it was expecting the stock 2100mah to be dying and ran FF3 for atleast 2 hours non stop on 1-5% until the battery actually gave out. On top of that it couln't decided how much it really wanted to say was remaining, it would jump up and down a percent or two, obviously confused of what to do. Whether or not its necessary to run it to this point is debatable, but with android or myself not knowing how much charge was actually left in the battery i did.
