23 1/2 hours on single charge

I just got me Evo two days ago, and flashed DamageControl's rom. I don't live in a 4G area, so I have that shut off. I generally don't turn on WiFi or GPS unless I'm actually using them. I did have wifi on a few times yesterday, but for a total of no more than 45 minutes. I have three email accounts, two that update as soon as mail comes in, and one that checks every hour. My corporate and google contacts sync as well as both calendars. I have facebook syncing in the background as well.
I did a decent amount of emailing and some web browsing. Even with all that I went 23 hours and 36 minutes before the battery went red and it told me to charge it.
I was worried with all the horror stories I heard, but that was pretty incredible battery life for my average use of the phone.

Is your battery completely covered in the orange HTC wrapping or does it have spots on the back where you can see the silver underneath?

It looks like it's completely covered. Although I would say it's red not orange. I couldn't tell you which batch it came in as I got it off of Craigslist.

People have reported that battery is better than the ones that aren't completely covered.

I too have the all red wrapper battery, did a 8 hour charge with the phone off prior to this picture.

I did jack **** with mine and was able to squeeze out 28 hours

I usually average 2 days on a charge, usually at least 35 straight hours. Having a second backup battery gives me more than 3 full days.

I think most of the problem lies in how the phone charges the battery; usually it doesn't charge the battery to 100%, but it thinks it has. Some days I get 5 hours out of my phone and other's 12 to 15.
I've tried every tweak I can find and run fresh 1.0.1, too.
I think I'm going to have to buy that 2 batteries and charger for the HD2 on ebay for $10; anybody have that link?

Drocap2 works excellent

I am relatively certain the Evo battery has a break-in period. My first week owning the device I was running:
Voice
SMSPopup
Push Gmail
Push Exchange
3G on / WiFi off
Did some gaming, light browsing, lot of texting, moderate usage over the course of a day.
I got about 8 hours tops before the battery died. That was with the screen brightness at HTC's "medium" level.
Yesterday, I had the same running in the background, did the same things except I also read a bunch using the Kindle app, and used GPS a bit, and I was at 60% after 26 hours off the charger. No special "tricks" like task killers (ew!) or underclocking hacks or startup killers or anything.

Huh...I am not where near getting that much. About to start my fourth week with phone and still in the 12-14 hours.
Are you all doing the charging routine or just plugging in? If I just plug in I definitely only get to about 10pm. If I do the charging routine I can get still have about 30% by evening.

Was someone having issues with the battery life on the Evo??? Cause I'm not.

My Battery Life WOW! *Pic for Proof*

Using Myn's ROM with the Battery Tweak, I have FaceBook syncing and I have 2 gmail accounts syncing along with Weather every 3 hours, Facebook every 2 hours.
Nothing else as of now and using Itching Thumb App.

Not needed. From the pic he attached it's obvious the phone was in standby most of the time.

Man, you even use ya phone?
What is with this obsession of battery life goin on 'round here? I say, as long as you can get better battery life than a stock rom, you've won. Keeping the phone on for a day or two without charging seems like a good idea, but everyday isn't the same, and one day you may need to use it way more than any other day..if you start that day off with only 30% just because you wanted to see how long your battery would last, then you really gotta limit how often you use your phone just so that it can make it till the next time your around a charger.

The battery needs to be charged? I bought my phone back in June. The battery is now at 70%. I figured I just had to buy a new one when this one runs out.

Barely used phone. Come on.

Display 4%? Is that possible?

I can go a full day and a half, 36 hours, without a charge and I am using the original sense android... and I use my phone normally, I text, read usatoday, tmz, check email a few times, use the xda app... and I have wifi on all the time! What's this beef with battery life on these forums? Mine lasts forever! I just have things update manually, I don't let anything run without my permission.
I do, however, turn my phone off the 6 hours I am sleeping.

wifi is on = low battery usage, atleast in my experience.

Indeed. I got 1 day and 19 hours on stock nonrooted 2.2 back. and i used it for some medium texting. and some gps applications...maybe 2-3 hours max awake time. i dont think you used it much...the excessive 3G usage from FB doesnt mean anything.

You should be able to get what you're looking for from the Spare Parts app.

According to mine, it's 122 min of screen on usage.
I had this scenario on my phone running myn's rls2 + king cfs #11 yesterday:
since unplugged - 24 hours
display on - 1 hour 25 minutes
charge remaining - 50%.

so i wanted to find out how long the battery would last on standby, and to my surprise.. it turned out to be nearly 58 hrs!!! that was on stock sense rom. non-rooted. and of course with very very minimal use. i basically just left the phone alone on my desk or in my pocket all day.
here is the screenshot i took back in july:
but that kind of battery life is unrealistic with normal usage. I am a moderate user (on the higher side), and i typically put my evo on charge everyday in the morning when i get to work (on weekdays). so, the charge on my phone lasts about 25 hrs with normal usage, that usually means about 4-5hrs of Awake Time. this is after rooting the phone. and i am using a stock rooted sense rom. i have had similar results before rooting the phone as well.
on weekends, i find myself charging the phone about 3 times (over 2 days), as the usage of the phone goes very very high.
i have a charger on my desk at work for the weekday charging, and a charger in my car for the weekends.
i have recently installed setCPU, and havent really seen that making too much of a difference, but that perhaps has to do with my usage pattern.
as pointed out in many a threads, signal strength is one major factor when it comes to battery drain. i live in Atlanta and i have great Sprint coverage where I am located, and that makes a world of difference.

it would help if you indicate the battery life that you were getting on stock or any other rom you were using prior to this. because there are so many variables that come into play as far as battery life is concerned. so that will help put your claim into some perspective

Long Lasting Battery!!

Hello Everyone,
I am seriously tired with the really little battery backing up time if I do heavy usage...So here is a really cool and serious method on how to improve the battery backing time.
Remember...Try the method with your Risk..You will the sole responsible if anything happens to your battery(although nothing will happen if you follow the instructions properly).
So here it goes:
1. Drain your battery to 0%.
2. Remove the battery.
3. In a polythene or a ziplock pouch place the battery in it and safely secure the pouch or polythene.
4. Now keep the battery in a DEEP FREEZER...(Brand Recommended: LG )
5. Let the battery remain in the DEEP FREEZER for 12-18 hours.
6. After the time has passed, remove the battery from the deep freezer, unpack it from the pouch or polythene, and let it come to a warm temperature.
In the mean time, while the battery is outside, there will be water droplets around the battery...dont worry its perfectly safe, but make sure that you clean them.
Now place it in your phone and charge it...You will see the difference...
How it works:
If you are a chemistry student or if you have learnt chemistry, the battery contains lithium fluid, which after a period of time starts to become more liquidish..so the bonds weaken, and therefore less battery backing time...If you keep it in the deep freezer, the bonds become more powerful and hence they 'Handshake' more perfectly. So therefore a better battery backing time.
I did this trick, and it really works...so go ahead and try it!!!

Anybody tested?wanna try,but I always get backfire by doing silly stuff.and as I rember.I saw a warning that the battery shouldn't be cooled below the temperature of 4°C

LoL.....batteries musnt exceed the temperature above 40 degrees....cooling wont harm it in anyway!!!! and i tried...it seriously powerups ur battery!!!

I get 4 - 5 Days out of my battery! So i don't have to do this YET. Really thanks for this. I will try it when my battery starts to be weak.

Do you have any screen shots of your battery consumption to back up you claim by any chance...

For a 12-18 hours there,I thought you weren't kidding.

On a side note, i have seen it guys put flash drives in the freezer for few minutes. I can't think of a reason why.

Freezing will actually damage the battery in the long run. The same holds true for totally draining it.
Now, this method might work in the short term but not in the way you're thinking. Freezing the battery will actually slow down the chemical processes, which results in what could be described as undervoltage at the hardware level.

Here is a thing.....download a battery indiacator widget...note the current voltage produced while its FULLY charged.....then after freezing and charging it to 100%, notice the widget again....it seriously does helps it and the battery....it doesnt harms the battery for a really long use....i did this, and noticed that i got a maximum voltage of 4193!!!....do test it!!!

should we start a poll for those who have tried and whailt results they got? Because if this really works it's very helpful, not to mention informative. (I do hate chemistry)

2-Mugen extended 3200mAh (+- 2yrs old)
these are my findings

as you can see it lost a bit capacity, i was very suprising to see it only lost about 400mAh in a period of 3 years
MugenPower 3200mAh battery
here is the result of the test of the Mugen 3200mAh battery.
(bought it used a year ago, so i dont know how long it was used before i bought that).
i did my research, this battery has been tested (new) and give arround +- 2400mAh in real-time though.. Mugen claiming its 3200mAh
It lost a but capacity but not by much as you can see it lost about +- 250mAh in a period of 2 years orso, so im very pleased with the performance
btw for informative purposes the screen was at full brightness in both tests
Please post your result also inhere so we can see the differences!

Yeah thats why i bought it used for like 25$ it had 2 cases (one with a kickstand wich was broken) and still with 1 month warranty left on paper .. so i contact them (dutch shop) and told them that my case was damaged so i send them my mugenbattery-kit and got everything back as new within a few days! and i dont know if they included a new battery also.... maybe it was a new battery but im not 100% sure ... i should have marked the battery before send it in
and somehow my CPU performance is performing better with the mugen battery according to the test

ill post my results tomorrow hopefully, doing first test now, but the second battery, supposed to be a extended life one, needs charging..
The app crashes at the end of the test, was looking forward seeing the results, oh well

I have ordered a new genuine battery since my old one is dying after 2 years of usage and flashing. I will do the test with the old and the new one to see the difference. So I just set the screen to full brightness and always on, switch on wifi, gps, bluetooth and leave the phone from 100% battery to 0% right?

No! turning on flightmode will do the trick (everything should be off otherwise you can recive calls and messages in the middel of the test)...then open Nova Battery tester app it will automaticly turn on the screen on its brightest level, before you click on "start benchmark" go to the setting and switch to "long" test (for best accurate result-from 100% to 5% if im not mistaken). then start benchmark, :good:
dont touch phone and leave it until its done

Is there any prove shows that the rapid charger will harm battery health and reduce the battery life? It is a vicious cycle.

I am in China and thanks a lot to our Great Firewall, maybe it is the reason that my phone is constantly awake. But normally, it will consume 10% of the power during the whole night. The discharge curve is almost a line with a -15 slope.

Your geographic location has nothing to do with it, and when the battery is healthy a normal drain is between 0.2 and 0.4%/h. This means that overnight you should expect a drain of 3-4% after 9 hours. If your phone continues to shut down by itself I'd say your battery is the culprit... especially if upon boot it shows a different percentage than when it shut down. Check your battery health first, and if it is OK ( say >85-90%), then install a battery drain app to find any wakelock, process or app keeping your phone awake. BBS or GSam are two.

Me too
It happens to me too.
Today my phone switched off when it was near 30%.
This behavior started with the last update to Android 7.1.2 .
I'm subscribed to beta program and until final version it never happened.

Agreed- and also why the battery is suspect. You neglected to show your Health tab which is where the estimated capacity is. No need to post another attachment, just tell us what the capacity is. If your phone keeps shutting down and dropping to zero, I would replace the battery anyway. Lucky for you the part is made in China and easy to obtain.

The capacity in Health tab is > 80%. The problem in China is we have too many batteries which claim to be original part, the price vary from several US dollars to 20 dollars. I bought a 5 dollars one and replaced the old one the week before last week, it is not easy. Now the capacity is almost 101%, the duration is longer than the old one, 10 -15% percent max.
And there was one time it shutdown itself several days after the replacement.
