[Nexus One Q&A, Help & Troubleshooting] Wylker:
I am looking for some help trying to figure out why my battery performance is SO terrible on froyo.

quick history:

-I installed the release candidate of 2.2 right when it came out and was seeing massive battery drain, from 100% to 0% over the course of 3-4 hours of mostly idle usage. I tried several different kernels to no avail.

-Rolled back to 2.1 and have been staying with different IR kernels and having good luck with them, average usage nets me about 2 days of battery life

-Yesterday I went ahead and installed kang-o-rama .9 using FRF85, updated to the 4.06.00.12_7 radio and tried it for a bit. Once again I was having major battery drain issues, losing 15% or so per hour while idling or making calls. I started to think that the froyo radio was the cause of my issues as kang would have had a different kernel and OS version than I had tried before.

-I rolled back to my 2.1-1 build (ERE27) and am back to 2 days of battery life BUT I am still on the froyo radio.

I am unsure how to troubleshoot this further, can someone give me some tips or direction to figure this out? I really want to use 2.2 but I just can't seem to get it working :(
[Nexus One Q&A, Help & Troubleshooting] Jack_R1:
Did you wipe between installations?

First guess would be an app that you're using which works correctly on 2.1 and gets stuck / endless loop / other anomaly while keeping the phone awake.
[Nexus One Q&A, Help & Troubleshooting] nexusdue:
Could be email sync on froyo
[Nexus One Q&A, Help & Troubleshooting] Wylker:
I wipe in between roms every time, and the battery drain was before setting up email push.
[Nexus One Q&A, Help & Troubleshooting] erikiksaz:
Maybe your battery is just not calibrated properly? Can't hurt to try this:

From an htc rep, cleaned up by rori:

The following steps should significantly extend the battery life on your phone.

1.) Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.

2.) Disconnect the phone from the charger, and power it off.

3.) Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.

4.) Disconnect the phone from the charger and power it on.

5.) Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.

6.) Disconnect the phone, power it on, and use it.

You need to use this sequence only once.

If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly, by dialing 1-888-716-3594.

Their business hours are Monday to Friday 8:00 AM – 8:00 PM Eastern
[Nexus One Q&A, Help & Troubleshooting] Wylker:
Does this make sense when it has worked fine on 2.1 before AND after switching to 2.2 (when it did not have good life)?
[Nexus One Q&A, Help & Troubleshooting] erikiksaz:
Won't hurt to try, will it? :)
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Ive noticed a significant decrease in battery life ever since i updated my phone to FRF83. I can leave it on at 100% and it drains down to 75% or even lower the following morning. It usually drains no more than 10% if i leave it running overnight.

I dont have any apps running in the background, and my task killer is set to auto kill 3 mins after screen blankout. Auto refresh is, and has always been on since the day i got the phone though.

I manually updated to FRF85B and the battery life is still as bad as ever. Ive never gotten this problem with android 2.1 or any of the earlier froyo builds. Someone care to tell me whats wrong? Ive heard others reporting that their battery life has increased after updating to froyo, why am i getting the opposite?
[Nexus One Q&A, Help & Troubleshooting] snlu178:
I have this issue because of my exchange server.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Ive never set up and exchange server on my phone. The only constant apps that should be auto syncing are gmail, calander and twitter, which is set to refresh once every 1 hour.
[Nexus One Q&A, Help & Troubleshooting] Mokurex:
Same for me, battery life sucks lately.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Then there are people reporting that their battery life has increased after updating to froyo. In fact mine was ok at first, until i started using FRF83 onwards then it all started to go downhill. This morning i woke up with the battery at 44% when i last saw it, it was at 90% the night before. It drained that much overnight and its not supposed to happen!
[Nexus One Q&A, Help & Troubleshooting] balenax:
Mine was very good since updating to froyo ( starting from first builds leaked). Its very good now too, better than before anyway. I used to run of juice by 9PM, now i have ~ 20% left with the same usage.

Check out what apps are consuming the battery, i got terrible batt life when i tried the droidx live wallpaper.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
App usage are the usual stuff.

Display being the highest, followed by android system, then cell standby, phone idle, twitter, android OS, launcher pro..etc

something seems to be sucking up my battery and i dont know what
[Nexus One Q&A, Help & Troubleshooting] EarthsiegeTA:
I'll be the first one, I guess - I blame the task killer. It's widely known that you shouldn't need a task killer, unless you have some rogue app.
[Nexus One Q&A, Help & Troubleshooting] drewstiff:
But if your task killer is set to auto-kill on screen-off, even if various apps restart then that should only be in the first few minutes and shouldn't reduce the battery that much.

I have taskiller installed but only for manual killing of problem apps (a rare occurrence) and I have noticed poor battery life since moving to FRF85b - didn't notice anything of the sort in the Froyo versions before 85b though.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Well i just uninstalled task killer, i'll leave the phone running overnight again to test the battery again. But from the looks of it. It seems battery life has improved slightly, but it could be just me.

Yeah thats true. It shouldnt suck up that much battery cos it only kills apps once. It could be an issue with the task killer causing it to drain the battery, because after uninstalling it i think the battery lasts a little longer. But i'll leave it running overnight again to confirm.
[Nexus One Q&A, Help & Troubleshooting] DarkDvr:
My quick story:

- frf72 and earlier - about 12 hours battery life for me. Used task killers, 2 emails on push. WiFi, BT off. Also tried juicedefender and setCPU. They made my battery life even worse.

- frf82+ (now frf91). Read up on how Android manages tasks and power. Got rid of all the task managers, setCPU and JD. Only use OSMonitor every once in a while to see if any dumbass app using up CPU in wakelock. So far none.

- EVERYTHING is ON. Wifi, BT, GPS - always on. I never use 2G, it's always 3G/HSDPA. GMAIL on PUSH, Exchange PUSH or 10minutes (no difference in battery for me)

- After a 24-hour test (from which 8 hours were on standby at night) I lost 80% battery life, so 20% still remain.

My advice: uninstall anything like setCPU, JD or taskkillers. Let Android handle that. Install OSMonitor and make sure nothing's in wakelock. Wipe cache if you want. If you're not getting 18-20+ hours, perhaps time to calibrate ur battery.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Thanks for the tip, just installled OSmonitor. The interface is pretty messy! But at least i understand whats going on. So all i need to do is keep track of which apps are at the highest load?

Is it really necessary to kill unwanted apps (Twitter, goggles, gmail..etc) because they are taking up RAM to improve battery life while idling?
[Nexus One Q&A, Help & Troubleshooting] baseballkyle:
OR you could just take Paul's advice and not use a task killer. My money is on him =)

FAQ: Why You Shouldn’t Be Using a Task Killer with Android
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Wow thats a very informative read! Thanks for the link. I too also thought that an unwanted running task means i need to kill it to free RAM in order to speed things up and improve battery life. Didnt know im actually doing it harm.

Looks like i'll ditch my task manager for good and have faith in the OS. ;)
[Nexus One Q&A, Help & Troubleshooting] derfasaurus:
Using LauncherPro Beta? I think some battery issues have been traced back to the way LP is handling updating widgets right now. Hoping for an update to fix it soon.
[Nexus One Q&A, Help & Troubleshooting] cr0wnest:
Well guess what. I just used the phone for an entire day and left it on since last night. It dropped down to 25% when i got home and was about to replace the battery pack. So it looks like task manager was the cause of the problem.

Launcherpro doesnt seem to be affecting the battery life.
[Nexus One Q&A, Help & Troubleshooting] derfasaurus:
Well it won't show up in the battery usage as affecting the battery. It has something to do with the widget updating not launcherpro. I removed BBC News, Beautiful Widgets and my Battery Info widget and my battery is now holding steady.

I'd be interested if you'd run an experiment, remove all updating widgets, notification widgets, etc and try again.
[EVO 4G General] teddykgb715:
Hey guys,

Apologies if this isn't the right spot for this thread, please let me know if that's the case.

I've done some googling and found people who were able to set the messages icon shortcut so that it launched handcent. But it seems that those were all on the Nexus One. Has anyone done this on the EVO? How?

Thanks so much! I don't really care for the Handcent icon.
[EVO 4G General] fireburster:
so you want to use the standard messaging icon but launch handcent with it? Just trying to clear up the issue.

Im using fresh rom and i have launcher, i used their icon for handcent in the launcher bar. Prob doesnt help you though.
[EVO 4G General] kiddecks:
Better Cut
[EVO 4G General] teddykgb715:
Thanks. I tried that but it kept fc'ing. Tried any cut and I'm halfway there. Changed the name but not the icon.
[EVO 4G General] xtripnic:
Not sure if this is what you're looking for but with LauncherPro you can customize the five shortcuts (phone, contacts, apps, messaging and web) on the bottom toolbar. You can simply hold down the messaging shortcut and link it to handcent while keeping the appearance of the icon itself unchanged.
[EVO 4G General] teddykgb715:
ok I have LauncherPro but when I do a long press on the messaging shortcut it does not have handcent as an option. Thoughts?
[EVO 4G General] AcIdC0R3:
Actually, I found some inconsistencies with BetterCut. You should try FolderOrganizer instead.
[EVO 4G General] Albaholic:
+1 to folder organizer
[EVO 4G General] teddykgb715:
At first I didn't think FolderOrganizer was going to do what I wanted, but I figured it out. However I had to use one of FolderOrganizer's icons for the messages, I couldn't find how to make the default icon work?

Thanks for the recommendation guys!
[EVO 4G General] BrianDigital:
alittle feature my girl showed me about launcher pro is that you can have up to 15 shortcuts on the bottom by scrolling left to right
[EVO 4G General] masterninja:
Yeah, you have to choose "applications" first...:)
[EVO 4G General] teddykgb715:
Ha. Good point.
[XPERIA X10 Android Development] mark28:
It seems like the update fix the battery issue for alot of people except for me. So I just want to ask if anyone with the new update and great battery life uses a twitter app and is on it a good amount of the time like me. Because I think that might be whats draining it because after the update I re-downloaded my apps but didn't set them up and I didnt have no drain in the morning,then I set up weather bug (which besides touiteur is the only app running in my background) and got some drain and decided to stop it from running in the background and removed the widget and the drain stopped. So I just want to know if someone has twitter running background updates and still gets good battery life because not being notified about my tweets will be kinda annoying.

*can you remove this thread, I wasn't paying attention and put it in the wrong section by accident*
[XPERIA X10 Android Development] Higgins12:
So u using Touiteur for Twitter ? From my own experience i can confirm that it drains Battery a LOT. Even when i switch off the Background updates it still drains. I use Seesmic and the Problem seems to be gone.
[XPERIA X10 Android Development] philcloh2o:
I use Touiteur on my X10 and it doesn't really seem to have that large of an effect on the battery life.
[EVO 4G General] lc3necro:
Ok, I know I heard / read some information regarding users having wallpapers dissapear after the OTA update, however I thought I wasn't a victim, perhaps I was.

However, I have lost 1,000+ images (mostly a large group of wallpapers I had downloaded and hardly looked through) off of my SD card. In addition to wallpapers random pictures are missing that I had taken with my phone.

Mostly curious if anyone had similar experiences? If so, did you deduce they were OTA related, or a specific app? I really don't want this to happen again, so I am looking for any information to help solve this :)

I am running stock EVO not rooted, for what that is worth.

Thanks in advance!
[EVO 4G General] lc3necro:
Update - Apparently all my MP3s have gone missing off my SD card as well :eek:
[EVO 4G General] Kykiskly:
Woww, this just started happening to me. I have not updated my EVO yet.

Is there a way to trace down what the devices does, like a log where it shows activities between the device and the SD Card.
[EVO 4G General] SMARTPHONEPC:
Just curious if you're using the micro SD card that came with the EVO or a newly purchased one, if so please mention card.
[EVO 4G General] Kykiskly:
I was using the one it came with, as a matter fact, I went to Newegg and purchased a new one 16GB Class 6. I already lost a lot of important pictures. I dont want to take more chances.
[EVO 4G General] SMARTPHONEPC:
Let's hope it's as simple as that, let us know.

Somewhat surprised people are still reporting this issue..
[EVO 4G General] mikevillarroel:
Mine is full rooted, not updated so far, with a A-DATA 16 GB Class 6 microSDHC Flash Memory Card and yesterday i lost the whole 100MEDIA directory so.....it seems to be a Evo issue
[EVO 4G General] Kykiskly:
Could it be an internal issue in the Device? I dont think this has to do with the ROM/Update the device is running.

We need to escalate this as a crucial issue.

I am running [ROM]EVO-NonSense(AOSP Elements), rooted using Toast Method 2, Amon RA, with Calkulin Radio+WiMAX updates.
[EVO 4G General] SMARTPHONEPC:
We should stay on top of this, I'd rather not have WTF moments or develop compulsions to constantly back up all files in some paranoid fashion..:eek:
[EVO 4G General] lc3necro:
I am using the stock SD card that came with my EVO, thankfully I was able to user some forensic programs and recover most of my images. I did narrow down the time frame of the deletions, however I was unable to determine If I had added any new apps to cause this issue.
[EVO 4G General] maback:
Makes me feel good that I did a SD card backup to my laptop today!
[EVO 4G General] mikevillarroel:
What appl did you use?
[EVO 4G General] lc3necro:
I used Access Data FTK Imager and made an image of my SD card then from the image recovered what I could of deleted files, and pushed them back onto the SD card when finished.

Link - FTK Imager about half way down the page.
[myTouch 3G, Magic General] dekkyy:
Today i wanted to root my new htc magic 32b. I used unlockers goldcard method to root my phone. This stage i made was successfull, but when i boot to fastboot mode ther was sapphire pvt 32b eng s-off h, radio 3.22.2.17 and spl 1.33.2010. So i flashed mytouch radio 2.22.23.02, when the phone rebooted i couldnt boot in to fastboot mode or recovery. No mather what i press the phone stucks at HTC MAGIC screen. So is it bricked or is there any way to fix this?

Sorry for my english.
[myTouch 3G, Magic General] TheForgotten:
Bricked, and btw why did you flash that radio because the radio you had was fine....
[myTouch 3G, Magic General] adavis159:
no, he had to switch the radio back to 2.x, a 3.x radio is for the 32A

have you tried to get into hboot mode (vol-down+power)? if that works you can flash sappimg from the goldcard again which will put the 3.22.2.17 radio back on, then you can try again
[myTouch 3G, Magic General] dekkyy:
Yes i flashed that radio because 3.22 radio is for 32A.

No i can't get in hboot mode. This is the screen where the phone stucks. View attachment 353338
[myTouch 3G, Magic General] dekkyy:
So is it bricked or what????????
[myTouch 3G, Magic General] TheForgotten:
Yes it is you have a very expensive paper weight :( :( sad face

Is there anyway to modify the bottom bar on Sense to add/customize ?

Sorry if this was answered before and I couldnt find it
[EVO 4G Themes and Apps] M@XLOL:
Could you be more specific? It probably is but imo it would be easier to use a homescreen replacement.
[EVO 4G Themes and Apps] vedavin:
ADW and Luncher Pro are nice, but in my opinion Sense looks better. I like the Launcher Pro's customizable bottom bar (launcher bar ?).......My question is if there is anyway to modify the Sense UI's bottom bar ?

Anyone care to answer ?
[G1 Q&A, Help & Troubleshooting] rodraf2573:
Hi.

I got a HTC G1 rooted. Originally I had a 2Mb SDCARD, and today i decided to buy an 8Mb SDCARD to increase performance on my phone. But I want to know what would be the best partition for the card of that size and for my current ROM (Complete Eclair 2.0)

So what would be the optimal:

swap-size?

Ext2-size?

FAT32-size? (doesnt matter cuz is the remainder)

-I got Complete Eclair 2.0 installed on my phone.

- The Android recovery system is: RA-dream-v1.6.2
[G1 Q&A, Help & Troubleshooting] lbcoder:
Where are you finding cards that small?

8 Mb = 1 MB, and is less than HALF the size of ONE typical picture taken by an average digital camera.
[G1 Q&A, Help & Troubleshooting] SolemnWishing:
I will assume that you mean 8GB (GigaByte) not 8Mb (MegaBit).

Here is my approximate setup and I think it should be sufficient for you.

~250MB Ext3 (Considering the average application is less than 1MB, but some can be a lot more, plus you have Dalvik-Cache storage, etc. However, 250MB should be more than enough. I used to have it go up to 500MB, but I needed the extra space)

~32MB Swap Partition

~Remainder as FAT32
[G1 Q&A, Help & Troubleshooting] lbcoder:
Almost, but not quite ;)

SI specifies a SPACE between the number and the units, hence 8GB is incorrect -- it should be 8 GB.
[G1 Q&A, Help & Troubleshooting] SolemnWishing:
Yes that is very true, thank you for the correction, I have indeed learned something new today hahahaha

Hello everyone,

I have been playing with my evo for the last 3 weeks and I love this phone.

However, earlier this week there was an automatic update on the phone and I realized that when I tried to connect to my wifi it would say "unable to start wifi". I cannot scan the network (grayed out) or anything.

Any thoughts.

Thank you.

Nim
[EVO 4G General] Robbio123!:
Yup - this is an issue

I have this same problem...started the same time!

If anyone has an idea as to what to do to resolve this, I'm open to suggestions. I noticed this issue a couple of days ago when I had an update pushed to me phone.

Would love to see this problem with the WIFI radio resolved...
[EVO 4G General] Skakum:
It's called return your phone. That update bricked my radios too, WiFi, 4G and Hotspot. Wifi had the same error and the 4G said "Failed". Sprint gave me a brand new one and no problems.
[EVO 4G General] coderli:
If it's rooted and was working before the update you can delete the following file

/data/misc/wifi/wpa_supplicant.conf

It worked for me.
[EVO 4G General] nimdivino:
brick?

Noooooo. Really? Darn.. I have a lot installed already. errrr. Thanks guys..
[neoTouch S200 ROM Development] ocman:
Hi everyone, as you know I am a little cooker for our devices ( although my roms are only for french users ) but I like to share with you some generics bug and solution found during my multiples cook/flash/use of the phone.

So here is what I found for curious lockups/reset/freeze solution and cause :

- Don't restore anything else than contact with pimbackup, otherwise, HTCMessaging would crash randomly and your device random reboots too...

- I your device keeps freezing and reboots randomly, tis could be the SDCard Filesystem to be corrupted, I have this case when flashing with SDcard in the phone, noticed it was corrupted because without the card the phone never reboots, in this case, remove SDcard, backup files on a computer, full format the card on the computer, put data back on card and sd card in the phone, enjoy.

For now that's all I have noticed with weird bugs, I someone here experienced this and can confirm or put his bug/solution, just post it!

Thank you for reading, and sorry for my bad approximative english.
[EVO 4G General] apollooff320:
This is pisses me off that it does this. Clockworkmod isn't wiping certain things correctly. I didn't ask for it to take over my other recovery method. Clockwork is ****ty and at wiping and couldn't even wipe my ass. I'm sure ppl that get a lot of FC get them because they used Clockworkmod to install their Rom.
[EVO 4G General] joackie27:
Are you using ROM Manager?
[EVO 4G General] apollooff320:
I've used it but havn't in a while. Today I wanted to install a different ROM but Clockwordmod pops up instead and this is without even using Rom Manager.
[EVO 4G General] joackie27:
Just install a new recovery then. I'm guessing when you've installed ROM Manager, you've also installed ClockWorkMod recovery.
[EVO 4G General] troyboytn:
use Ra's recovery, it is reliable, tested and proven to be much better than clockwork
[EVO 4G General] apollooff320:
that's what I was using then Clockwork magically took over.
[EVO 4G General] nunyabiziz:
Uninstall ROM Manager and flash RA's recovery back then. No need to talk bad about Clockworkmod.
[EVO 4G General] apollooff320:
oh yes because it's just that simple. I can say WTF I want about it since ppl need to know it doesn't wipe correctly. Hell even Devs are starting to recommend not using it since it doesn't wipe correctly. Hell try to do a Dalvik wipe and see what happens....NOTHING. It doesn't wipe it at all. Anyways I found the option to flash the recovery back to what I had at the bottom of Rom Manager.
[EVO 4G General] mrmomoman:
I don't think anything magically taken over is a real assessment but that is just my guess. I think a mistake happened from the end user end. Trojans and Viruses happens the same way. It's not always intentional but often enough its is the fault of the user. Crap happens.

A minor hiccup :) You have a long weekend to enjoy your phone,ROM or BEER and friends!

I choose BEER and FRIENDS this weekend. Everyone take a break!!
[EVO 4G General] apollooff320:
well I found out it's a feature to take over as recovery from reading the clockwordmod thread. It happened in one of the new updates.

Doesn't matter now I have what I need and I'm happy to know I can flash it back to the recovery I like through Rom managers menus.
[EVO 4G General] M@XLOL:
magically took over lol
