BATTERY SUCKS AFTER FROYO UPDATE !!!

[b0ricua]

I have had the same or better battery life after the Froyo plunge.

 

[DirkBelig]

While I haven't done the battery recalibration thing yet, my battery life has fallen back to first week levels of terrible. I've been running without task killers since a hard reset a couple of weeks ago and was easily getting 14-18 hours of nominal use before hitting sub-20% battery level; now it's there in about six hours and the warmth is pronounced through the Body Glove case. Very disappointing.

Updated to 2.2 this morning around 10 am. Have been using the device non-stop since then playing around with every feature and made three phone calls (about 10 - 15 mins each) and the battery life seems the same or a little better for me.

 

[JERAVICIOUS]

my battery life seems to be the same, 10+ hours. That's with texting, internet, photos, etc. So I am happy that the update did not compromise the battery.

I'm so sick and tired of all the worrries about battery life and turning this off and re calibrating this that and the other ... I bought 2 sets of the Ebay batteries ($20 delivered) which means i have 5 batts now ... I want to use the phone in all its full glory so I do ... I always have at least 3 batteries including the one in the phone ... If I am in my car I plug it in ... If i am at home I plug it in ... I can go at least a full 24hrs of HEAVY use with three batteries and Im talking a couple of full movies and all ... I don't mind ... I carry a satchel everywhere I go anyway ( I am mostly on my motorcycle ) ... No worries ... No worries ... No worries .

Well I am not worried about battery life..... That being said my battery life is actually worse now going on day two with 2.2..... It's not major but it's noticeable since I took it off the charger at 10 this morning and at 3 I am at 55%... For what I do it will make it through my day's 99.99% of the time.... Not a big deal as my car has a USB port and I can always plug it up at my desk as well......

Edit: @Solo1.... I purchased two back up batteries even before the June 4 release date and I have the wall charger that charges the battery with out the phone so that I "DON'T" have to worry about battery life...

I've also noticed with the new update that it's a little more picky about which USB plugs you use. It won't charge on my laptop at work, and it did on 2.1 without an issue.

What/where can I find this battery calibration you speak of?

 

[netcub]

Phone has been unplugged 8 hours and 29 minutes, Ive made a couple calls today (short ones) and sent 5-10 text messages, took a couple pictures, and maybe browsed once or twice for a few minutes. Battery is @ 15% now.

I've seen a dramatic decrease in my battery life since the upgrade. I was getting 15-20 hours with what I consider moderate to heavy use now I can barely get 6 hours. The circular update icon is nearly always on and I cannot figure out for the life of me what program is causing it!!! It is tremendously quick with froyo, but due to the miserable battery life it is useless.

To those who were getting 6 hours of life before try charging off of your computer rather than off of the wall plug. I found that the supplied HTC plug did not work well, but plugged into the computer or using an old Blackberry or other aftermarket charger (rocketfish I think) got me much better life.

S-P

EDIT: Just figured out that my Exchange server appears to have gone down at my office which rather than throwing a visual flag it just kept trying to update. With that knowledge I can't say anything about the battery life at this point. Hoping when I get it fixed tomorrow it will all be better.

Battery life is most definitely worse. Not hugely so, but definitely noticeably and measurably - Over the course of several multi-hour tests and two, 24 hour tests, battery life (for me) is right around 23% worse, +/- std deviation of 5.6%.

That being said, I explored around in the phone and its settings and came up with a couple observations:

All the things you previously disabled for better battery life, have automagically become re-enabled with the update - Gtalk auto sign in, calendar and contact syncing, full stocks/weather/FB/etc syncing like gangbusters. Its wise to go back through any "battery optimization" process you did before and re-do it, step by step to make sure you're not forgetting anything - the running processes and system configuration is, for the most part, just like it was when you brought your EVO home the first day.

Those of you noticing better performance -
Its true (obviously - and any benchmark and real world use will tell you so) but even with the optimizations and JIT compiler additions this is at the expense of higher battery use. -System Panel shows a consistent higher average processor use and clocking. Whereas under 2.1, if just left to its own devices, the phone would stabilize at a minimal power use (but awake and active) state of about 5 - 12% processor usage and clocking would bounce around a little between 245 MHz and 425 MHz, with an occasional spike up into the low 600's. Now, with 2.2 under the same conditions, processor usage averages around 10% with 7% to 17% as the highs and lows. Processor clocking is through the roof - I haven't seen it drop below 600 MHz yet; average hovers in the low 700 MHz area bounded by highs and lows from 650 MHz to 810 Mhz, with spikes up into the 900's. BTW, I made all these measurements *after* re-doing all my battery saving tweaks and rebooting.

Higher Partial Wake Lock states. I'm not quite sure what it is yet, but my guess is, whatever is making more use of the processor is also holding the phone in a partial wake lock state longer and more often. The culprit shows up as "Android System" so it could be nearly anything from the system itself to some other app keeping requests open for system resources - more investigation is needed.

All (or most) of the above observations could be very system specific, being different based on cell signal strength, wifi, apps, other settings, etc. so its not surprising that some people seem to be seeing better, worse, and the same battery usage - sometimes all at the same time.

I agree after 2 days I am seeing a pretty even 20% decline in battery life (in my everyday use) but A. it still easily gets me from 7 in the morning until 10 at night no problem and B. Before the EVO came out I ordered a backup battery and a charger to charge with out the phone just in case....

Probably also part of the reason Sprint didn't want us to have this build right away.... I still think this was the test build and one of the testers released the site to download the link.... It's not bad, I have found it to be a pretty solid build with only a few minor bugs to work out..... Even when they settle on a final build you can almost mark your calendar.... with in a month or two there will be an update to 2.2 as more and more bugs appear when it's released to the masses...

 

[emeraldayotte]

I'm doing about the same 12-14hrs. Not complaining as it's MUCH better than my Pre's battery life.

Those of you who are getting over 20hrs, can you explain what your doing? I've done all the normal battery saving tricks (mobile data not always on, GPS off when not using, screen around 20-30%, etc). I've even gone as far as using the under clock method through setCPU.

I think it's really going to depend on how you use the phone... As stated above I was going 16 hours with around 40% remaining before the update now I am below 20% after the same period.

MY... Typical day consist of about 90 minutes of web browsing per day, receive about 20 - 30 e-mails (e-mail is set to 1/2 hour updates) send about 5 - 10 e-mails out, take about 20 pictures, upload 5 - 10 to Facebook and e-mail about 2 - 3, 30 -45 minutes of talking, 50 - 100 text messages, check and update/comment on facebook probably 10 - 20 times per day (Facebook sync is set at hourly) weather is set at every 3 hours update, The only radio I keep off is WiFi and 4G (dont live in a 4G area) unless I am at home or uploading a large video file then I use WiFi... Screen Brightness is set to the middle setting and I only turn it to bright when needed, I use a dark black back ground/Wall Paper as that uses less light/battery (but not enough to make a difference.. I used a live wall paper for a week and the difference was minimal) I don't play games at all... I have that Free "Lets play golf" but after 2 weeks I have only played it twice.... I do use Advance Task Killer but I do not let it run all day... I click on it 3 - 4 times per day just to clean up what is running including ATK and I typically kill every thing when I use it....

Well that is my usage.. Hopefully that gives you a better idea on how I have gone 16+ with 20 - 40% remaining...

 

[Brainerd]

It also depends on your cell and data signal strengths. I'm guessing that my lower than average battery life is partly due to my okay, but not so great, cell signal.

Those with 12-16 hour days on their Evo probably have a lot of bars and use a lot of WiFi. There are other factors, but sometimes we forget about the most basic element. Signal strength.

With that said, I wish the EVO was better at managing it's power consumption in poor reception conditions.

Well you're using your device way more than I am and still getting better battery life. I constantly give 4-5 bars of signal wherever I am.

The major difference between our usage patterns is that you are using the internet more and more phone calls. I do however have my exchange email syncing as items arrive instead of one a schedule. I'll try that and see if it makes a difference. Also I've only had my Evo for a week so maybe it hasn't conditioned the battery completely.

Thanks though for the info and hopefully I haven't completely hijacked this thread.

I'm a heavy user... power user if you will. I don't expect my battery to last more than 8 hours the way i use it (like a former blackberry addict). That being said.. i updated to Froyo and for the first time ever i burned through 3 batteries in about 15 hours..... I can't even keep up my 3 battery rotation, because the third battery died just as the first one was still charging (im using the ebay batteries for two).

The major thing i noticed is since Froyo 2.2 my uptime is exactly the same as my wake time.... even when the screen is black.

Im going to do a hard reset tonight and try again tomorrow.

Re: Battery Life After 2.2 Update

you guys are crazy complaining about your battery life. i am lucky if i get over 6 hours.

Same here with the stock battery. I bought one of those nop name Chinese 1800mah ones. Which should have given me another hour or so. I ended up with almost 3x longer life. I can go all day, then leave if on my desk, then be at 30% battery in the morning. The stock battery, 6 hours. I was always near a charger. USB or wall.

Evo is Evil, and I love it

 

[PM-Performance]

Yea my wake times are high again and up times matching like it did when the phone was first released . I'm sure the next patch will fix it. We are on unofficial builds so I'm not stressing it yet

 

[ghostkilla1388]

I hope after froyo the battery last longer. still waiting on a evo here

 

[Makad]

16 hours and 48% later, it is the same as 2.1 for me. I always get over 25 hours.

25 hours, whats your secret?
