tl;dr: Got a new battery. I've seen lots of posts around on how to reset the battery stats so the phone "knows" how to accurately gauge how much batter is left. Is that necessary with a new battery?
I upgraded to stock pie about a month or so ago. Since then, my phone randomly freezes and reboots 5-10 times per day. It's not an app causing it as it does it the same thing in safe mode. It happens when the phone is plugged in also. I thought maybe it was the battery, so I got a new one installed. It's still doing it even after the new battery. I've seen lots of posts around on how to reset the battery stats so the phone "knows" how to accurately gauge how much batter is left. Is that necessary with a new battery?
What Is your screen on time with the new battery? do you recomend replace the battery?
Jumping in, 6 months old device, battery still has full capacity.

I don't really remember what it was before I had the battery replaced. SOT was definitely quite a bit lower than when new. The phone was over a year and half old and I'm a pretty heavy user so it was charge cycles A LOT. IIRC, Accubattery showed it was holding about 75% of original charge. It definitely feels, like the new battery as a couple more(if not more) hours of SOT now.

Hi there.
Was wondering if u have replaced the battery yourself. And it survived the procedure alright. I am now having the same stats - accubattery shows 75% health.
Should I go for it? Scared as hell

I just received this in the mail yesterday, and I think that it's worth $30. The battery definitely lasts longer. I'm only on my first day of use, but have had the phone on with normal use and bluetooth on all day (9+ hours so far) and I'm at 60%. Had I remembered to turn off bluetooth this morning, it would have been closer to 70% left since the bt accounted for 21% of total battery usage.
Also worth noting... The wall charger seems to properly charge the battery. I drained my original 1500mah EVO battery down to 7% and then placed it in the charger. It charged for approximately 6 hours. Normally, when charging it from empty in the phone, it charged much faster. I'm not a battery expert, and I also could be mistaken, but I get the impression (from reading threads and using the phone and previously owning an iphone) that the HTC software is not properly charging the battery and that is contributing to the miserable battery life right out of the box. Obviously changing setting in the phone software help quite a bit, but I feel like this charger and battery setup help significantly. I'm going to throw the fully charged original battery in tomorrow, and see what kind of performance I get out of it. I'm betting it will be much improved.
Apparently I can't post links on my thread because I am a new user. Just search ebay for chichitec and check out there store. I'm not affiliated with these people in any way. I just happen to be pleased with their product and figured I should share this for any other users that are frustrated with battery life on their EVO.
I just got it (though from another seller).
Figured it was worth the $20 to see if a different battery can help my situation.
I'm at 24 hours up time 3 hours of awake time and still have 26% left. Plus I've got two fully charged spares. Battery problem solved.
Did you actually get red batteries?
They're not exactly the same with the HTC logo, but they are red.
What are the eBay item numbers you guys used?
This is from the same seller for one battery and the charger. He basically charges $10 for each item.
http://cgi.ebay.com/HTC-EVO-4G-BATT...ewItem&pt=PDA_Accessories&hash=item4aa320f7db
And I am convinced that the poor EVO battery life (stock) has to do with using the phone to charge the battery. I charged the original HTC battery with the included charger and I am at exactly 40% battery remaining with 24:37 up time and 3:05 awake time.
So much better than before.
That's why people are using the method from the forum where they charge their battery 10 times to "condition" it. That definitely helped me, but using this external charger is even better.

Are all the people who brag about 24-31 hours battery time sitting with like 3 hours of actual up time for that period? if so no wonder i dont last any where near that i am usually done at 12 hours with about 6 hours up time.
I consider 3 hours over 24 hours to be very light usage just wondering if that is the reason why no matter what i do i ant get any where close to some of these peoples times.
I wasn't trying to brag. I was just happy to finally get what I consider to be a great improvement over my original battery life. I wish I had more time to use my phone that many hours in the day. Seeing that I don't, this setup works good for me. I know this isn't amazing battery life given my light usage, but so much better than stock out of the box. I haven't rooted yet, and I'm not very conservative with settings that drain the battery.
And to answer your question, yes, that's why your times are shorter, but it seems like you should be getting more. If I have a day where I get more up time, I'll post the numbers.
my battery is dated at june 30 2010 is it time to get a new one? i have decent battery life but it used to be even better
The time for a new battery is when the battery is dead. Any other time is personal preference.
Doesn't matter when the battery was manufactured. It depends how many full charge cycles you went through.

Not true. Lithium-ion batteries start corroding the moment they are manufactured. 2 -3 years is the max on one.
The old battery I had only lasts 6 hours so i got a new one and it's much better.

mine would barley get 16 hours with light usage so that isnt too bad but i could probably get better with a new one
i got a new battery for my vibrant yesterday and it wont charge past 80 percent. however it sits at 80 for a whille then starts to drain normally.

Batterys are Simple= NOT
OK, This info started back in the days of NI-CADS, now were onto lithium-ion Battery's, Polymer, and so on!
trbobuick is right but in a wrong sense of stating they corrode!! What they do is the composition of the materials over time change, depending on how hard or easy the life of the battery's been and how much use in cycling it has gone thru!!
Also, alot of people don't realize that a battery will last longer being used, than sitting there without a job= not being used!!
FACTOID: All battery's irregardless of make, [Except the new Dry capacitive cells, which don't apply to cell phones], are subject to a finite life! And the quickness of dying or longevity of that battery depends on a few factors listed below!!
1: The material its made of internally!! Some are better made than others, so naturally, some brands are more durable and have a higher life span than others!!
2: The way it is handled and charged from the very beginning, meaning cycling the battery all the way to almost depleted, and then recharged back to full = setting the memory of the cell, so the entirety of said material is fully trained so to speak!! And continuing to keep doing that thru-out its life span= the discipline to wait till it gets low enough to start it on another re-charge cycle!!
3: The conditions the battery is used in= cold or Hot temp's, a battery in cold conditions, wont retain and discharge as much amps, as opposed to a battery in warm to hot temps, however Extreme temps/very HOT also quickly degrade a battery, yes there is a happy middle sweet spot= normal conditions= longer life of said battery!
4: Don't OVERCHARGE A BATTERY!! once its full, UN-plug it, keeping it connected to the charger destroys the memory and over heats it and literally cooks it= the internal material its made of will degrade much faster if it doesn't cycle down to a normal temperature again!!
Now In our scenario of cell use, one more thing must be done, and that is to use SW= app, to calibrate the battery cycle!! Key word here is CYCLE!! However all it really does is prevent excess amp draw and mainly for the Battery display to show % correctly! It really doesn't do much for the battery itself!!
The only other two other things can be done to extend battery charge cycle, is to reduce the number of Unnecessary apps running in the back-ground!
Think of this as in the Apollo 13 mission scenario!! Referring to the movie, where they worked on reducing the amp draw, Key word here is Amps, not voltage!!
And choose a ROM that has better utilization of power consumption from the battery over-all!!
So again, Analogy wise, Its like how you drive your car, either your pushing it to its limits with poor P-Maintenance, or you keep your foot outa of it, and maintain the fluids regularly etc!
I use a 3500 MA battery on my vibrant and it will go for 2 to 3 days depending on use, before it gets below 25% But I conditioned it brand new from the Get-GO to increase its charge cycle and longevity, even though I'm using a somewhat power hungry ROM!!
However, the only thing that's wrong with it as an after market battery, seems to be lacking some kind of signature/code that the OEM Samsung battery's must have, because when I go to Flash/MOD my phone, Odin or CWM wont even work right, until I change to the OEM Samsung battery, then all is happy!
When I'm finished I change out the battery after a power off, and things are Good to go again!!
And we all thought Battery's were simple HUH = LOL
Thank you very much for the battery info

If you want 100% you need to shut off the phone when it stops charging, when its off plug it in until it says 100% then pull the battery and pop it back in and charge again until it gets 100% rinse and repeat this 10 times or so, and reboot...your charge should have gone past 80% - you can do this until you hit 100% but its not really all that important unless you're trying to calibrate and get a proper 100%
Thanks for the great info "dseldown" I really have to stop charging my phone over night i just have been getting lazy over the months.
Hello guys,
I have a GSM Galaxy Nexus running the latest Android 4.2.1 Officialy from Google. I hae bought an original extended battery for it, but the issue is that it seems that it holds less juice than the original one, that came with the phone.
With the default battery, i get around 3 hours of screen on and with the extended one, i barely get 2:40 minutes. Tried this a couple of times.
What's the matter with it ? Do i need to calibrate it somehow ?
I have the same battery and had the same issue. After using it for about a week it started working better. What I suggest is charge it all the way up and then use it until it completely goes dead then fully charge it again. Do this a few times then you should notice the difference which isn't huge but I'm averaging about 4-5 hours more than standard now.

I did this allready, and there's no improovement.
I have been using this batter for over 1 month now.

With Li-ion batteries, this should make no difference what so ever. It should get better over time. From what I've researched, you should never let a li-ion battery fully die. When it hits 20% - 30% fully charge and then don't charge again until you hit 20%. There are only so many charging cycles on a battery.
You might have something constantly running in the background that is eating your battery. Try juice defender, it drastically improved my stand by time.
What i was saying:
The stock battery holds a charge of ~3 hours of screen on time
The extended battery holds a charge that lasts less than 3 hours witch is strange because it haves a bigger capacity.
Is there any way to reset the baattery stats ? Or to reset the battery count ? Something like that ?
The whole "wipe battery stats" thing found in CWM is useless. Confirmed to be by a developer at google.
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
I see. Anything else i can try ?
So, my phone's battery life is overall quite poor for the most part. some days it absolutely burns through my battery with little phone use, and other days it gets decent battery. i downloaded better battery stats, and for example. today my phone drained at about 10%/hour, but yesterday for example it drained at about 3%/hour. And today i did not even use my phone that much. Please help, as this is getting really annoying.
Here are some screenshots of my battery stats on two bad battery days

I know it looks like dolphin burned alot of battery, but that it just because it was practically the only application i opened and i used it for a couple minutes which i normally wouldn't do. then i few hours later, this was where my batter was at, and i swear i pretty much did not even touch my phone at all! http://imgur.com/NIfYnkl

Yeah I noticed something interesting as well. I have two batteries for my GS3, one is the stock battery that came with the phone and the other is a 4200 mAh battery from Hyperion Electronics. I decided to test each battery by charging each to 100% on different nights and not touching the phone overnight to see what my battery drain was
Night 1, I tested the stock battery and over night I went from 100% to 40% in a span of about 8 hours. That's a 60% decrease.
Night 2, I tested the Hyperion battery and over night I went from 100% to 98%. A total of 2% decrease in the same span of time.
Now yes I understand that the Hyperion battery is essentially 2x the battery capacity as stock, but just by simple ratios you'd think that since the stock was a 60% decrease that the Hyperion battery would be a 30% decrease, but it's not. The Hyperion battery is literally 1/30th of a drain than was the stock battery.
Something's wrong here and I wish someone could give a straight answer as to why these two batteries are demonstrating dramatically different results.
Seem like the battery deceased so fast after 2months of usage.
7+ hrs usage... Still alright...

Is this the first time it happened or this is what's happening all the time now. If it's first time then the system could've read wrong voltage/charge. But if it's constantly happening then I'd say something is wrong. If you want I'd say call up Samsung or your carrier and have them send you a different unit if you don't feel comfortable.
Mine was doing this at 3% for awhile and suddenly it's back to shutting down to 1%
You should be more concerned about leting your device reaching that low on battery, it is very bad for batteries to almost completely discharge, that is really, really worrisome, if for any reason your usage is that demanding and you can not plug your device to an electrical outlet, get a powerbank or a battery case

I second this. Folks don't understand just how bad discharging their batteries is for the battery longevity. This is why you see so many folks that kill their batteries in 2-3 years. Even a 3 year old battery will still retain a good amount of its original capacity if you do not expose it to full drain and recharge cycles. Top up and top up frequently. This is the best way to ensure a long battery life.
Pretty sure the battery has a system built in to monitor and manage real full depletion.
It probably doesn't deplete to the point of damage.
As far as what percentage it dies on, I mean that percentage is just an algorithm to estimate battery life. It's probably not very precise especially when a percentage is the value output.
I try not to let mine drop below 20% and charge to 80%
