I have decided to move this post from the issues thread to a dedicated one to give it better visibility. If no one else is getting this problem then I will probably return the device.
I have the excellent "devstate" today plugin application installed which gives the battery charge level in 1% steps. When I say slow, it takes around 3 mins to increase by 1% which means it will take 4 hours for 80% charge (too long) when this is the case, the back doesn't heat up.
I have seen it charge much faster on one occasion i.e. around 1% a minute and the back was warming up (this is logical if more current is flowing) I was wondering the cause of the slow charge is that the device thinks it is connected to a pc and the charging current is limited. Also when you plug the cable sometimes the menu pops up asking whether you want to enter activesync/disk drive mode but doesn't on other occasions. There doesn't seem to be any pattern to it.
Another observation is that a soft reeboot occasionaly gives wildly varying battery levels for example before reboot the charge might be 100% and straight after the reboot 90%, or 83% before and 100% after. Interestingly before turning on the device for the first time I fully charged the battery, but up on boot up it was reporting 60%! (maybe it didn't charge at all when it was switched off and 60% was the initial amount of charge the battery came with) Have I got a duff battery or some issue with the device itself?
I seems like the battery charges fast up to 75% at around 1% a minute but then slows down to 1% every 3 to 4 minutes. Maybe this is the charging profile for this battery. Has anyone else noticed this?
Here are a couple of threads from the diamond section regarding the sort of issues I am experiencing but there doesn't seem to be a conclusive fix.

Could people please answer the following questions to help me decide whether I have a faulty device/battery or some ROM issue which all of us have. I have the stock UK touch pro ROM 1.90.405.1 WWE.
1) If you fully charged the battery before powering on for the first time, what was you battery charge level immediately after power on?
2) Have you noticed fluctuating charging rates?
3) Soft reboot gives different battery charge levels.
Just a quick Q, which charger are you using? Can you just post the amp / volt data printed onto it for us?
I am using the one that came with the touch pro, model no TC P300, its output rating is 5V at 1A. Input rating 100-240V
I have also tried the mda vario III charger and I get similar results i.e. fast charge up to 75% then slow afterwards.
As i stated in the other tread with the "Raphael issues" i have the same problem.
When i use the shiny new charger with the "usb-mini usb" cable i takes 7-8 hours to completely charge the device. (output is 5V-1A)
However, when i use my good old Hermes charger, or any other 5V-1A charger, it goes to 100% in about 3 hours.
Mine charges up to 90% from 10% in less than 3 hours after which it stays @ 90% (According to the built in battery meter of the device) forever. Is it a faulty battery or its supposed to be like that?

And do you get varying battery levels on soft reboot?
3 hours is probably what I would get i.e. "75% at 1% a minute = 75 mins" PLUS "25% at 1% every 4 mins = 100 mins" giving a total of 175 mins.
question is that is this behaviour normal for touch pro or only present on
some device/battery/chargers.
I also have another issue, this time regarding interference on speaker, see this thread:
http://forum.xda-developers.com/showthread.php?t=419761
If only my touch pro has these faults then I want to replace it asap, especially when having paid £500 for it.

Yes i do get varying levels on reboot, but i got that with my Hermes and Magician too. So i wouldn't worry about it. Usually when you softreset while it's charging you get a higher battery reading then you should have, but it wil drop after some time to it's real level.

This happens when its not charging. I don't get this with the vario III. Maybe it is ROM dependant. The other concern was after having charged the device fully when switched off, it reported 60% on power up. I might let the battery drain to a low level then charge when switched off to see whether it charges at all. Some diamond owners were also reporting this.
Hmm, got the same thing tonight with my Hermes charger, has been charging for 6 hours and still not fully charged, now at about 80%. Very strange. Are there more people experiencing this?

This didn't appear to happen to me on the first charge, but I turned it on immediately after putting the battery and SIM in place, and then I charged (I don't remember what the initial battery charge was). I've not noticed such wildly inaccurate readings after reboot either. I haven't specifically checked for inaccuracy in the battery meter, but I would (probably) have noticed such a big difference.
Have you tried to do a full discharge and charge cycle? This is necessary after around every 30th charge to recalibrate the gauge so that it is as accurate as possible. I know yours probably haven't gone through 30 charges yet, but it may be worth trying.

This is normal for lithium-ion batteries. The last 20% or so can take as long as the first 80% to charge.

When charging I usually leave mine overnight, so I think I've only charged it once during the day, and then I think this was through USB while connected to the PC so it may have been a bit longer than 'normal' (3-4 hours) for that reason. I'll keep an eye at it next time I do it during the day.
Six hours plus sounds far too long though, do you have a chance of trying the battery in another device, or another battery in your device?

Nope, don't have a second Touch Pro around here, but this is really annoying, I need a fully charged battery in the morning. If this is hardware related i'd return it to get a replacement.
hmm, this is interesting.....so just to clarify we are seeing slower charging with the bundled adapter: which is essentially an AC to USB power transformer?? If the USB port on that (yes i know its power only) is capable of supplying only a standard ammount of juice then your battery may charge to 100% as slowly as from a pc or car charger..
..id like to perhaps see if i can meter the current and voltage coming from it but would need me to cobble together a breadboard with the relevent power points.
Is the hermes / kaiser charger charging it fully in less time?? (to clarify)

Yes I drained the battery till the phone switched off by itself but still have this problem. I suspect there is a problem either with the phone itself or the battery as supposed to a ROM issue. I thought all the clever charging circuit is in the battery these days and it's the battery which reports it's charge level to the device too. If this is true then probably the battery is faulty but I am not going to buy another one just to find out. I'll try to get a replacement for the touch pro tomorrow when the shops open.

It is, but even so the gauge (in the battery) needs recalibration once in a while, hence the full discharge/charge cycle every 30th charge or so (other than that it is recommended to charge li-ion batteries often, and not deplete them fully).
Your next port of call is probably to see if another battery makes a difference.

Today I charged my phone from empty to full while connected to the PC, which took around 3 hours 30 minutes (phone not used except to check charge levels towards the end).
the charging cycle on mine has been a little erratic too.
I put it on charge at 9pm last night, at 6.30 this morning it was at 88%. 9 hours and not fully charged!!...still, 3 hours later and it's on 87%. so I think its more a case of requiring a few charge/discharge cycels to settle the guage down a bit.
This night it fully charged in 5 hours. While yesterday it wasn't completely charged in over 8 hours. There doesn't seem to be a pattern in this.
Yesterday it was showing 48% battery level at one time, a soft reset later 28%, another soft reset and it was 24%. Today I have sent it back for a replacement. Can those people affected by this issue please state where they bought it from, in order to figure out whether it might be a faulty batch. I bought mine from clove technology in the UK.

Mine came from Expansys.be, please let us know your new unit has the same behaviour.
Will do if I get a replacement one, they have satisfy themselves that there is fault first. Will probably take around 3 days. I miss my touch pro already.....
Oh well back to the vario III for the time being, seems cumbersome already in comparison.
Hermes Charger

Whilst I don't have any exact figures to hand, my hermes charger took about 45 mins (Give or take a little.)
I've been using the standard Raphael charger today and charged from 50% and it's still going after 1 hour 20 mins and only at 90%
I know the final 80% takes a lot longer, but even so.....
Is there any way to get this thing to last over 10 hours with moderate/medium usage? I mean I hate to compare, but I was able to use my iphone 4 hard periodically through the day and be at 40% around midnight, but I have to stay using my captivate very lightly after about 10pm, and I usually unplug around 12 to 1pm..
I don't want to have to sacrifice majors perks of why I switched to android just to get a full day out of it. I've tried a lot of the suggestions I'm the forums, but nothing makes a notice difference, or makes it a fame changer as to where I'll get a full day of moderate internet/media usage
Thanks in advance.

Have you tried draining and recharging the battery as other threads have suggested? I usually unplug around 9-10am and I don't get battery warning until near midnight or later.
I keep seeing people complain about the battery life constantly.. but to me coming from my bb bold it seems that the battery is lasting way longer then i expected.. first couple charges i let the phone drain down till it shut off, and then charged it 100%.. its still new to me so im constantly playing with it and changing the menus around.. i try to make sure almost everything is closed when im not using it.. cause im sure that eats battery life..

I did it once, but I booted back up the phone a few minutes after I plugged it in, will leaving it off while it does a full 100% charge noticeably increase battery life?
Do you have widgets updating frequently? How frequently? Maybe just too many updating widgets. I get about 18 hours with the screen on for 4.
18 hours also
I'm getting 16-18 hours of use with about 4-5 hours of screen time. Better than expected.
Today I used my phone as much as I used my iPhone 4 on a regular basis. My phone has been off the charger for just over 12 hours and I have 70% of my battery left.

I'm around that too, I use a black background to save power and I have about 5-6 hours of screen time and I watch a movie on it every day (treadmill at the gym)
I only get low battery around midnight
I use advanced task killer and set it to when the screen is off to kill apps, aggressive mode, I can go about 20hrs before I need to recharge. 5-6hrs screen time.

One thing about android is it has true multitasking. Combined with some apps which do NOT close properly and continue to use up CPU this can drain your batter very fast.
In the battery Info your TimeSpentAwake should be ~ the same as Display on time. If not something is not closing properly. Use OSMonitor to check which program it is and either uninstall it or make sure to kill it with task killer after using.
I have the M110S (Korean Galaxy S - I get 16-18 Hrs with moderate use, but M110S comes w/ 2 batteries so i just swap )
Yeah based on people who are getting good battery life mine is absolutely terrible. I am on my fourth full discharge. I have had my phone off the charger for 2 hours and I'm already at 87 percent. I listened to about 45 minutes of cached slacker radio and like 2 posts on xda app

Just to comment on my battery life. I got my phone saturday (2.5 days ago) and its been on the whole time with medium usage. When I got the phone the pamphlet inside said "fully charge before you turn on" and thats what I did. My battery is at 41% and the only time that I have charged it since is when I am connecting it to my PC for a very short amount of time. I have had great battery life so it is possible. I am very impressed with it.
Yes...my battery life has been good...
Screen brightness all the way down (auto brightness off) *same for the browser brightness
Screen timeout 15 secs (annoying sometimes so maybe 30 secs)
No window animations
Power saving mode off (no point in having the lcd adjust if its already as low as it will go)
I also dont have any widgets that update in the background, however i'd imagine one or two wouldnt affect the battery much
These settings have worked out for me and i use the phone moderately with 2 hourly updating email accounts.....

Battery life for me has been decent. I consider myself a moderate user and I can go from 7:30am till I go to bed at night without dying, but its close. Coming from an iPhone 2G, where with the same usage I could get 2-3 days on one charge, its a little disappointing. But it is what it is I guess. I have heard horror stories of EVO's only going 4-6 hours on a full charge, thats ridiculous.
But what gets me is all this nonsense about fully discharging before charging back up every time. These are Li-ion batteries, they are not Ni-cads, they will not get a "memory" if you dont fully discharge every time. Yes, its good the very first time, to fully charge it before using it, but after that, it doesnt really matter.
Also, one more thing I noticed. The phone will stop charging the battery the second its fully charged. So if your phone reaches 100% charge at like 2am, it stops charging at 2am and you are then going from 2am till whenever you take it off charge in the morning. I noticed this the other day. As soon as the phone told me it was fully charged, the battery icon turned into a normal battery icon even though it was still plugged in. So its possible that the phone is going for 4, 5, 6 hours off charge before you even wake up. What I do to make sure I'm at 100% when I leave, is when I get up I unplug it, use it for a minute then put back on charge while showering. Then when I leave for work, I know its fully charged at 100%.
I guess I'll be switching out phones at Best Buy today as well. Phone keeps losing 30-40% overnight (more like 5 hours max since I'm a night owl) even with everything turned off. When I do get back to a 90% charge before I leave for work at 8am, I'm usually left with 30-40% by 5pm after 15 texts or so and a few emails.
I am fairly sure all new batteries have a chip in them that regulates the power. So you HAVE to run it down to 0-5% and charge it back too 100% several times before the battery is even calibrated for use. That has to be why its 50/50 battery sucks battery is great, just let it drain and charge it again.
battery life simply not acceptable
Hey guys,
I know many people post on battery life.
Here is my situation.
I do not care about beauty, but functionality is a must.
I am in the hospital from ca 6am to 7Pm and I have Q4 call meaning every fourth night its to midnight. That is simply a fact of my life.
My requirement:
I need my phone to last for this duration without recharge.
1.)
I don't need or use widgets
2.)
I don't need or use a wallpaper other than a solid black background.
I do need and use:
the GSM radio and wifi both need to run the entire time and reception is what it is.
My applications of use:
merck manual, dynamed, epocrates the usual in my boat.
I really really want to use this phone, but battery life wise only my blackberry with extended battery and my iphone 4 can hack it.
If any of you have any suggestions on what I could do plz let me know. My last resort is carrying two batteries, but that would frankly be admitting that this phone is inferior to the iphone 4 which can hack a 20 hour usage day in my setting.
(I absolutely cannot turn wifi or 3G off both must run)
I am open to all suggestions including the task killr controversy or anything else constructive one may have. Any extended size batteries out there for the captivate?
Thanks a bunch in advance.
(Having had my secretary spend 4 hours rooting the phone and sideloading Merck manual is a testament to the pathetic entity that is AT&T by the way. If you have professional apps from an institutional subscription you cannot download the software from the market...)
PS: My secretary is not exactly a hacker so forgive the 4 hour timeframe.
I consider myself to be a heavy user!! I like to text, browse the web, listen to music (either from my own files or streaming,) check email and comment on facebook all throughout the day. I did that perfectly fine with my Bold 9700, that battery lasted a full day or more.
I had an iPhone 4 and my battery would not last my 8 hour work shift!! I either had a bad battery or who knows what was going on with that phone. I didn't even leave the apps running...the phone was nice, but that battery killed it for me. I don't understand how some people got a full day out of it.
On the Captivate the most I have gotten has been around 10 hours of use and that's not even using it how I normally like to. I stop charging it at 8:30 and my battery is 100% around 10am I'm already in my low 90's or upper 80's. I don't have any widgets updating, I have a black wallpaper, I don't have the haptic feedback on, and I sync email hourly.
Could my battery be bad?? How can some of you manage to get 16 or so hours out of it??
I have been having problems with my battery life pretty much since I have had this phone. I downloaded spare parts app to give me some insight because I have also noticed several times phone seems warm even when screen has been off for some time.
As of right now today, to give an example, my phone has been unplugged for the last 10hours and I only have 44% battery left. Says display is responsible for 71% of battery use yet screen has only been on for 44min of that time (and I have the brightness turned all the way down). According to spare parts "other usage" my "running" time is cause for 35% of batter use at over 3hours.
With these things in consideration I feel that there is something that is stopping the phone from properly sleeping due to the phone being warm at times display has been off for a while and the contrast between screen on and running time. Partial wake usage doesn't show much running under it as most listed items have only a sliver of a bar showing.
Can someone please lend me some guidance on how to further troubleshoot this problem?
i mean that type of battery consumption doesnt seem irregular to me...im at close to 10 hours for the day and have 59% left.
Are you in a shaky signal area? Thats one reason my phone gets warm. especially if its a fringe area where it cant decide between a 3G signal or 4G signal.
In spare parts there is a option for partial wake lock. If something is stuck at 100%, then you know you yuo have a rogue app thats causing your phone not to sleep
But can you confirm it being normal to see 34% time running under other usage settings for spare parts? Partial wake usage as said doesn't show much keeping a wake lock going.
As for signal, not too sure, very rarely if ever see a 3g change over. Is usually at 4g and occassionally hitting edge.
WOW, you get that good of battery out of yours? that seems epic haha, i get 3-4 hours tops.. i mean i abuse it, but still..
I charge mine at night. Ran it from 7am to 12am and it was at 34%.
Yeah see...7am to 12am and 34% remaining? No way I get that.
If it werent for the results I'm posting regarding "running" percentage from spare parts other usage and the screen on time I would just accept it as a phone deemed to have bad battery life, but it seems to me like something is going on and I guess I'm looking for someone to confirm or dismiss my suspicions.
Maybe I'm also a little spoiled coming off my G2 that was rooted running CM Rom and CPU ramping/cut down which in combination gave me, under the same amount of use, a situation where I was getting home at night and still having 40-50% battery left in comparison to the 15% I commonly see now.

once some custom kernels come out that let you uv/uc/oc then i would say you can expect the same type of results..i just went on a trip with a friend who has a g2 and he was constantly crying about his battery dying, (stock), where as I only had to charge mine on average 1.5 times a day with moderate to heavy usage. I find this battery phenomenal compared to all the other android devices ive owned and tested
damn!
i charge mine every other day.. hehehe i dont abuse it or anything though.. just regular internet every few minutes or so.. i have the BETA juicedefender installed guess that helps a lot. data is off when the screen is off, set it to agressive..
here is the app hope it helps...
I noticed the same problem,i brought this phone on saturday and was very impressed with the battery until yesterday night I noticed the same thing, my phone was at 50% and I had it sleeping then I get the battery low notification 10 minutes later and the back of the phone was real hot. This can't be normal cuz I have the same apps installed from 2 days ago and I was using the phone heavily even using mobile ap and still didn't have this problem, if you guys find a solution please share it with me.
Does this program drain battery? Had it on, and my battery was draining. Just want to make sure. I really like it to replacement stock launcher, but if it's going to kill the battery, might as well not keep it.
I use go launcher on both my phones and it doesn't use any more power than any of the other launchers do
Damnit, eerywhere I go Reg, your there to tell me that nothing I use is effecting my battery:/ this is my 3rd phone, I have no idea what I should do, factory reset?
my battery life sucked too when i first got the phone. i had been lurking this section since day one before i got the phone so i was aware of all the battery issues and possible fixes. so when i finally brought the phone home the first thing i did was made sure i did the setup wizard and immediately after i did a factory reset. then after doing the wizard again i restored all my apps and started using the phone. quickly noticed my battery life wasnt great so i downloaded the battery monitor widget and saw that the phone was constantly using 100+mA at all times. It was then that I decided to factory reset AGAIN. After doing that and reloading all my apps everything was fine. my phone uses 2mA at idle and fluctuates sometimes into the hundred but it always goes back down as it should. I also charged my phone to 100% then booted into clockworkrecoverymod and deleted the battery stats to insure the phone is reading the battery capacity accurately. No need to drain the battery and recharge it, thats just a waste of time. Now my battery is awesome. I lose 2-3% per hour idling and 1% every 10 minutes or so in actual use (assuming im not doing anything thats constantly using data connection).
Moral of the story... You prolly need to factory reset more than once because it didnt work for me till the second one.
Just for the sake of comparison.. My Vibrant loses 10% per hour idle and 1% every 2-3 minutes in use. So the battery like on the G2x is double if not more. Unless you have a defective phone or battery I dont see why the factory reset would only work for some people.
Okay, I think I'm going to do the factory reset, I won't lose my superuser functionalities or root right? Or BloatFreezer apps etc.?
You wont lose root. All your apps will be gone though so make sure you back them up with either titanium backup or mybackup pro. if i were you id install battery monitor widget and monitor that for an hour or 2 letting it idle to see if its still sucking juice for no reason and also use it for a good amount of time to make sure the mA go back down when you let it idle. that way you dont restore your stuff only to find the reset didnt work.
Sounds good, thanks for the advice man, will try this tomorrow!
So far it's not bad, it's at 1ma really when I'm idle, but as soon as I walked into my school building, I got 20ma, wtf? Is it maybe because my connection in school sucks? The cell standby went from 48% to 78%, can this be why?!

Yes. Weaker signals will make your phone poll for a better signal more often. It'll be searching for other towers more frequently.
Correct. So dont pay it too much mind. The phones power useage will fluctuate. What's important is that it's not consistantly using 100+ mA. All the time. I've seen my mA usage go up to 40-50 while idle yet when I checked back moments later it was back down to 1. This is normal behavior.

Okay, good well right now it's constant at around 10-15 ma, woke up at around 9 with 97% and now at 93% at 11:30 with a few text messages and browsing, I actually think that's a lot better than the past few days. Let's hope it stays that way
Consider your battery drain fixed then. I should note that my idling at 1-2mA is when connected to strong wifi. Your slightly higher consumption is more than likely due to less than great signal strength. Never the less.. you should find that your battery life increases dramatically. Even with 3 bars of 3g here at work I only lost 5% in 3 hours of idling.

Kudos, I will report if anything changes, because it is only 2 hours into the day
So this has happened twice now. I'm running on ARHD 4.1.0 w/ Bricked 1.0.
My battery will be running normally, normal drainage, etc., and then it'll just drop from 90 to 70% in less than an hour, and normally drain for another hour or so, and then at around 60% just die. I can't attach a screenshot since normal screenshot apps aren't working and the stock function keeps producing invalid images, otherwise I would, but it literally just looks like it got to 60% and instantly dropped to 0%, there's just a vertical line of missing percentage. I took my phone out of my pocket, expecting it to be around 40 or 50%, and it wouldn't turn on. When I hooked it up to the charger, it took a good 5 or more minutes to even respond to the power button. Do I have a bad battery or just incredibly out of whack battery stats? I have never had this problem with an android phone before, and I thought for sure one full charge overnight would fix it, but I guess not because it happened twice. Any suggestions?
Edit: I use an app called battery snap to monitor the battery level and temperature with a widget, I checked a snapshot history while it was charging and for a few seconds it was at 0.002 volts. But then it jumped back up to 3.897 or something around there. That doesn't sound very good to me.

I don't know much about this, but I don't think battery stats have anything to do while the phone is dead. Even if it does, the phone would at least respond after a minute or two, not 5..
My suggestion is that you can order an Anker battery which is kinda cheap ($15 I think) and try.
You won't loose anything
Edit: Try wiping battery stats, do a full charge, fully discharge and fully recharge again and see if it helps (In your case I don't think this will help, but huh, let's hope ;D)

Thanks, I'll try it. I flashed the new cm7, since I just got tired of sense woes. I read battery life on this was amazing, and I'm hoping it was just a bug with the kernel/rom I was using. Battery stats would've been wiped when I wiped for flashing this ROM, so I'll do a full battery cycle and cross my fingers. My only thought is that maybe, if the battery stats were screwed up enough, it thought it was at 50 or 60% but really it was more like 10%. I remember having issues after I flashed the custom kernel, where before I flashed I was at 70%, and when I rebooted I was at ~10%, and I was like what the hell? So it ended up dying on me, but then I turned it back on and it said 50% or something around there. And then it functioned as normal until it died again, for real that time. Hopefully it was the kernel causing the issue. I'll run a few tests with this and see. If it is the battery, I'll try t-mobile for a warranty replacement of the battery.
The battery measurements seem to be really quirky on this phone. When the phone is idle it seems to drain anything from 50ma to 400ma for no particular reason. You cant really rely on the % too closely
Yeah, I've found the percentages to be pretty inaccurate. Hardly an hour and a half on the battery and it's down to 84%. I did play a game for like 10 minutes and the screen has probably been on for 20 or so, so that's not incredibly unreasonable. I'm just waiting for that dropoff to 0%, if that happens again I'm thinking it's hardware, because I'm running an entirely different ROM and kernel right now.
So it just happened again, went from 42 to 14 after reboot, had to remove battery and reinsert to fix. But other people have reported this issue on cm7. So, I'm thinking maybe that it's an issue with android 2.3.5 or the kernel for it, since it's happened on both arhd 4.1 and cm7, both 2.3.5 roms. I'm going to try and flash faux's cm7 kernel over it and see if it fixes it. May or may not, might be a long shot but worth a shot, I'd rather not switch roms for a third time in the same day.
