Help Possible Battery Fix from HTC

I made the mistake of jumping the gun today and installed the leaked "official" froyo update.

Since then my battery life has gone from decent on 2.1 to absolutely terrible on 2.2. To put it in perspective -- my battery went from 66% to 18% in 30 minutes with no clear or obvious reason why.

I reset my phone and reinstalled only the apps that i use often and it's the same. However, I went to the movies tonight and figured I would try the turn off background data thing while I was in the theater since I didnt need to use my EVO. Surprisingly, when I did that, it seemed that the battery life was fine. I had 35% going into the theater and 32% coming out of a 2 hour movie.

I ran that system panel and the other app mentioned in this thread and it seems that the highest CPU process is android system info. The highest mem process is android.process.acore. I'm not sure what any of that means, but I also tried the GSM / CDMA / Update PRL trick just now to see if that has any effect. Hopefully, it does!

Is there a way to go back to 2.1?

Thanks for your time and help.
 
This was as I'm getting ready to go to bed:

yeah, I know it isn't the crazy 20+ hr uptime people are getting by disabling half the phone, but what makes this so great... I changed nothing from my 2.1 setup that would only last 6-7 hours. Froyo doubled my battery life!

There's still 2 android.process.acore processes there as well.

I think that's just normal for Launcher Pro. Remember, when I glitched it was because I'd gotten it backwards and thought you were NOT running that one.

Congrats on the restored life!

Does it actually take a while, even if the screen is off, for it to "fall asleep?" I would think it starts right when you hit power to shut off the screen.

That's entirely up to Android and your configured options for stuff.

Hi, welcome to the forum!

Yeah, don't sweat it, you're not stuck or even screwed.

Besides, the real deal is coming out really soon now and anything we missed they're liable to have a handle on.

We mostly all got a big battery boost with the 1.47 official update, I expect these little kinks to get solved by them or your friendly neighborhood spiderman (read: all of us working together).

Hey - there's always a few gotchas with any update, but a day after they're solved, they're forgotten and you'll be happy as a clam.

Promise. ;)
 
Way too early to tell for certain, but it certainly seems to have greatly increased my battery life.

The real test will be Wednesday night when I go back to work.
 
Waiting for the official OTA release.. I can't believe that HTC won't do something to improve battery life, since it's the cause of most bad press about this phone.
 
Its seems that there are mixed results so far, but i must say it is greatly improved for me. I did hard reset before and after the install of 2.2.

Here is where i am at after my first full charge:

9h 47m 19s since unplugged

cell standby 33%
phone idle 32%
android system 20%
Display 6%
Voice calls 4%
Compass Leveler(i was playing with it a while) 3%
Dialer 2%

Up Time 12:04:59
Awake Time 2:55:10


ALL THIS AND I STILL HAVE 68% LEFT. Sorry for the caps, but i think it was an improvement. Also i do use advance task cleaner pro.
 
but running 2.2 since friday and my battery life was almost cut in half not doubled. Not sure what I am doing wrong have changed nothing since the upgrade. will see what happens maybe it will improve by the end of today.
 
Agreed. After doing everything else, hard reset has now completely fixed problem. I am now getting best battery life ever. First hard reset since launch day.

This morning, before reset, I watched my phone go to 50% in an hour of almost no use. Henderson the reset.
 
I'm confused. You're condemning an entire manufacturer because of an update that was publicly stated to be an unofficial build that shouldn't have been released to everyone?

Yeah. that makes sense.
 
My battery life tanked after the update and doing a hard reset didn't help though it did get the stock browser working again which was my only other problem. I tried all the other cures found in the forums to no avail. I finally started going thru my widgets last night and deleting them one by one and it seems the culprit was the "Battery Left" widget. If not left on the charger my phone would go from 100% to almost dead overnight but this morning was only down to 98% and after some browsing,app installing,etc I'm down to 96%. I re-installed the widget and excessive battery drain commenced immediately so I'm positive I've found my problem. Check your widgets! :cool:
 
After doing the battery fix by toggling background data and a few resets, I can say that this update is not that bad. I am still finding some bugs but nothing too major. I am pissed about the change in the calendar reminders being changed for no apparent reason. I hope the update tomorrow will iron out some of the bugs. Some people are saying this update was not worth it but JIT alone is worth it to me. My browser flies and that alone is worth the update. My apps open fast and the phone runs much better with 3d games. I just hope that if this is the final update they come out with a followup update to fix any annoyances that are found.

Now if only I could get 4g to work in my area, even though I am surrounded by it. This phone has such a weak 4g antenna.
 
Just a follow up from me. After hard reset this morning, I am at 44% after 4.25 hours. Never since launch day have I ever had a battary last more than 4 hours.

I suspect a hard reset in 2.1 may have achieved similar results. So can't say it is Froyo. Yet I keep checking with jaw dropped as I have never had as good as I seem to now after hard reset.
 
In anticipation of needing to do a hard reset either before or after I install the update......what type of things do I need to backup, write, down etc before a hard reset? I am concerned because my People/contacts are NOT syncing up correctly with Google contacts and I really dont want to lose anything. Plus pictures, a few documents, etc I do not want to lose.

Thanks, looking forward to Froyo. I am finally gettin ggood battery life out of my phone (and heaven knows if I'll remember what all I did to tweak and adjust to ACHIEVE that!!! ) and hope Froyo doesn't send me backwards.

Brother, I think you just explained the entire battery thread!

Ain't hindsight great:

  • We flail around with radio settings in 2.1 - like the phone's not in its right mind
  • We flail around with plug, unplug charging - all the while saying, Gee - it's like the software for the battery has lost its mind
  • We flail around with SD card formatting - because the software must've lost its mind
  • We flail around with task killers, we flail around with root, we flail around arguing about that those things and custom roms for the battery win in 2.1

And now, because we knew we brought this on ourselves, we all try the factory reset - where before, we didn't.

The symptoms were no different.

Pardon me, the floor seems to be approaching me at high speed... ROTFLMAO!!

BTW - I still advocate the CDMA->GSM->CDMA auto(PRL) thing after reset (I think) and I have definitely removed every vestige of every task killer or cleaner. I put an Applications widget from the Shortcuts->Settings on my desktop and just use that if I feel I need to (like, for self-inflicted gunshot wounds while I tinker with apps) because it is just so much better in 2.2.

Oh yeah, where was I? :lma0:

I'm finding it so hard to believe that people are only getting 3-4 even 5 hours from this phone unless they have every radio (wifi,4g,gps,bluetooth) on constantly with live wallpapers and everything updating every hour. I'm not saying it's not happening, it's just hard to fathom.

I'm going to turn on EVERYTHING and see how long my battery lasts.

Word to the wise, the best way to maximize the battery is to go bare bones minimum and then add back the things that you actually use and need. I think that will go for any Android Phone or any modern phone.

I agree with all the last too. But some good reason to want to delay reset. Mybackup pro only does some. And until I can get paid apps again, I havr lost some significant functionality.

Still, the performance and battery performance now makes it so well worth it. Why I poat. Hope others will try. I know they will be pleased.
 
My battery life seems to be the same with 2.2 which probably means it's better since I've been using it more after the update. My battery life was already great and I haven't done anything special. No task killers, no turning off radios or whatnot.

Everyone's mileage varies - that's life. Some people had no trouble with different things, while others did.

But strictly for thos drifting on the unhappy raft, we now have what's shaping up to be a valid, simple procedure to get them into the happy boat.

w00t!
