I've noticed that whenever I just stick my phone on the charger and unplug before 100%, my battery life sucks all the ass...and when I put it back on the charger and charge it to100%, it stays on 99% for the LONGEST time. Is that the same for everyone else?
And when I say my battery life sucks all the ass...usually when I charge overnight and unplug, I can do nothing with the phone but listen to music and my battery will hold like a champ. But whenever I unplug without hitting 100% I'm losing like 20% in one hour. For example, I charged my phone from 30% to 85% and unplugged. Left my house for an hour and when I got back I was at 60% and all I was doing was listening to music. The screen was only on long enough to change songs every now and then.
Also, charging from 30 to 85% was really fast...so fast, I felt uncomfortable (not really, but it was faster than usual).
So idk what's going on with my phone. If other people are noticing this, please lemme know so I don't feel like I'm the only one. And if it is just my phone and I may need to take it back...I might just have to bite the bullet on this one because I don't want to get a phone that has that loss of service issue...I'd rather just remove battery indicator pro so I don't see the battery percentage and just assume its always better than it really is just to make me feel better.

What I mean is, I'll use my phone all day and get down to like 60%. Then I plug it in for 30min or an hr with mixed use, and take the phone off the charger again (car charger) to use some more. Let's say the battery is now at 84% after being on the charger. I don't use the phone much after this charge and go to bed with about an 80% charge with the GSM radio on all night. I wake up about 6:30AM and check the battery level in the systems folder and battery status and it shows, 80%. About 10mins later, I get a notification for a task reminder. I go to dismiss it and look at battery status. The battery level is now 89%!? So now I don't know if it's actually at 89% or if it's really lower and giving a false reading. Very frustrating. Previously I had issues with the battery being drained when in flight mode on another ROM though. Just wondering if anyone else is having similar issues or if it's my battery or device.
BTW I'm now using Premium 2.0 w/o cube.
Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?

ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.
I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.

My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.
This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?
I'm not sure if this has been posted yet, but when I unplug my phone after charging it overnight, it gets to 90% or so in around 30 minutes without use, and goes down at a fast rate throughout the day. If I charge it and unplug it exactly when it hits 100%, I can use the phone fairly regularly and it will take around 2 hours to get down to 90%, and depletes from there very slowly. What's the reason for this, and is there any way I can get the same battery life when leaving the phone overnight?
Running CM7 with incredikernel, although my phone has been this way with countless ROMs and kernels.

Short answer: Yes, you will see better battery life, and no there is not really any foolproof way to make it work if you leave it on the charger after it hits 100%.
Long answer: The Incredible has a battery saver feature built in that prevents over charging by cutting off charge to the battery when it hits 100% (actually 96% according to the people who figured all this out and are way smarter than I am) and doesn't let it start to recharge until it hits 80%. The reason, when you take it off in the morning, it drops so fast is because it is no longer actually at 100%, but has dropped to a legitimate ~90% since having hit the "100%" threshold.
There are some kernels out there that do allow "trickle charging" meaning they keep the phone at a legit 100%, but I don't think many have seen much success using them with the Incredible.
I get around this by charging a bit at night (using anywhere between 80-100%), leaving it off the charger until morning (I usually drop only around 4-5% per 8 hour night) and plug it back in while I get ready and eat breakfast. This usually puts me around 95-100% depending how much I was able to charge the night before and seems to be a much more simple way to handle it than bump charging in my opinion.

I've seen similar topics regarding the quick drop from 100 to 90%, but the battery life as a whole seems to be much longer when it's taken off the charger immediately after it hits 100%. There's so many topics on here, I can't find exactly what I'm talking about, so it's difficult to judge. I'll definitely try the tip in the second post though. Thanks!
It will charge it up to 100% but it won't stay there if you keep it in. It'll let the phone die down to 90% then it'll keep it at that level.
So yes if you unplug it when it first hits 100% you will have a full 100% battery. If you let it sit for much longer than it'll be at 90%
It's been said that leaving it on charger for a while after fully charged messes with the battery meter.
I always bump charge. Charge it full while on then power off and charge till green lights on. Def gets me more batt life. Im getting 24+ hours on a single charge under normal usage with UD 3.1.1.
