As same as the title, I found several posts said that the battery stat would be incorrect and it should be wipe after a new Rom installed.
My question is:
1. Aren't we do the 3 wipe before installing the new Rom and the battery stat should be also wiped?
2. Why the Android OS needs the battery stat file to determine the battery status?

Rooted Droid 1, running LFY 1.9 with it's 1ghz kernel, SPRecovery. Had a weird issue recently; the phone displayed that my battery life was at 40%, then probably ~30 minutes later it was down to 20%. I wasn't using it during that time, I just unlocked the screen to check something. Anyway, I opened my browser and within a minute or two I got the "15% battery life remaining" message, prompting me to connect my charger. I decided I would allow the phone to just die and shut itself down. So I waited ~45 minutes and it went down to 10%, then almost immediately to 5%. I turned on the GPS just to make it drain faster... I watched a one-hour television show and when it was over, I glanced over to the phone to see if it had died - nope, still on. I turned the LED light on, leaving the GPS running for ~25 minutes and it finally powered down. Then I plugged it in to charge and left the room. Came back in about 2.5 hours later and picked up the phone - it was very hot. Unlocked the screen and checked SetCPU and it was running ~135?F but it immediately started cooling down. It was fully charged, however so I unplugged it. I went to bed shortly thereafter and the battery life displayed 90% as I set the alarm to wake me up the next morning. I happened to wake up shortly before the alarm was set to go off and I picked up the phone to disable the alarm and noticed the red 'charge me' light blinking - unlocked the screen to see 5% and just then it powered itself down.
TL;DR -- Phone only got hot that one time, phone hasn't gone dead in stand-by mode again like it did that night. Battery drains at a seemingly normal rate based on my regular use from 100% down to 40%, then it rapidly drains after that, always skipping 30% and when it gets down to 5% it stays alive for quite a long time under heavy load. Is there a way to 'teach' the phone how to check and calculate actual and remaining battery % and to display it correctly? Is it kernel-related? I heard somewhere about doing a 'battery wipe' but I am unsure what that entails and searches are proving fruitless for me so far.

Tried it this morning anyway, figured it couldn't hurt. Charged the phone, gave it a nice bump charge, and then booted into recovery and wiped the stats.

View 5 Replies View RelatedAnyone finding their Desires battery life has decreased with Froyo installed? I used to only go into the orange after a full day at work, now my battery died at around 12 Midday (Unplugged it 5 hours before) - I haven't been playing around on my phone or anything, this is just idle use.
Went through all my settings and all were the same as before. I'm NOT running any Task Killer or AutoSync software. Running stock OTA Froyo, never routed my phone before or after.
I did unrEVOked 3.21 and applied OMJ's 2.2 netarchy kernel ROM. I am not sure what my battery life was at this point but I was now on 2.2 after using eclair 2.1 for so long. I wanted to go to the new stock kernel so reupdated to OMJ's stock kernel 2.2 ROM. I also added back the Sprint TV Widget. Ever since, I have noticed a major drop in battery life. I usually get 30-40 hours on a single charge. Now I'm down to about 10. It is REALLY screwed up. I have CWM backups of all of the phases, including my 2.1 ROM. I might experiment rolling back if nobody else has any better ideas on how to debug?
I am using ATK but I make ATK kill itself so it is only there to help me kill procs. I noticed QIK and FRING seem to run all the time now whereas they didn't before I updated them. Not sure if that is related. TOP app shows me nothing special but system_server taking up most of the CPU like maybe 6% peaking while idling. Otherwise I just can't figure it out!! I used to be the one bragging about how awesome my battery has been (running original OTA1 which let me still use unrEVOked 1.0 to get simple root all this time). I am finally on 2.2 and I'm disappointed with battery life now. WiFi is WAY better but that is about it. My Nexus One does not suffer from 2.2 battery blues.
I just rooted tonight and installed SetCPU. I want to use it for the battery saving capabilites. I created a profile for when the screen is off and activated it, do I also need to check "set on boot" on the SetCPU main page?

1. How can I remove apps that are pre-installed like soundhound, talk, stock. The remove option is greyed out.
2. Can I create a sub folder in the menu tree and move like games into one. I have created a sub folder on the home page, but cant rename it from 'folder'
3. My phone picks up WiFi signal at home everytime I am in range. Does this mean WiFi is always on, searching. My experience from my E71 showed me this kills battery. I seem to struggle to get more than 10 hours life from the battery, what gives.
I have an HTC one developer edition, I did an advance wipe of my phone because it wasn't charging, it said that USB Host mode was on. It only charged when the phone was off. I decided to wipe everything but the pictures (or so I thought) but once it finished the wipe the entire OS systems was erased, know the only thing I can do is enter TWRP. I just bought the phone!

View 5 Replies View RelatedI was flashing CM9 from CM7 on my Motorola Defy, botched it up intially due to a slip of my finger which led to me to Clear the cache first. But then I restarted the entire process by Clearing Data -> Installing -> Flashing Kernel and so on...
But when I tried to clear the Dalvik Cache, the phone didn't delete it. It didn't give me a message that it wiped the cache, but it didn't say otherwise either. This led me to believe that the cache just didn't exist anymore.
As a result, I'm unable to install apps - Says there is no memory and I need to make more. Also, everytime the phone comes on is treated as the first time. It takes me through the whole process of Setting up an account and everything. This has rendered my phone obsolete.
what exactly does a data reset do? Does reformat (a) partition(s)? If so, which? If not, which files/directories are removed; What exactly IS deleted? Second, how would I do a data reset through ADB?
My screen is basically broken. It works for a split second when first starting up (cold boot), and flickers off and doesn't turn on. Everything else works. I'm planning to resell for parts; I think I've invested way too much for this phone (screen broke before, and then got stolen, and now broken screen again). I would like to erase all data on the phone. I would normally do this through Clockwork recovery, but can't on the account of being blind due to broken screen.
I did come across this thread, but it still left me questions. Is reformatting system necessary? How would reflash my ROM via ADB? What about wiping Dalvik cache? Is dalvik stored within the cache partition?
As for the phone itself:
Samsung Galaxy S Epic 4G (Sprint)
RandomROM Thunkderhawk 3.5
USB Debugging enabled.
I was just flashing a new ROM for my gio, and made sure that i did a factory reset, wiped cache partition and wipe dalvik cache. but when i went to wipe the dalvik, CWM froze for a bit, then showed the yes/no part for like half a second, then kicked me back to the main menu. It does this every time. What to do? or should i just reflash it?

How do I wipe without bricking my device?
I have a rooted EVO 4G that has worked fine until now, I backed up the phone to my PC with a full copy back up but did not back up the ROM Manager like I usually do, I tried to restore the phone and it will not place the saved calander with the copy and paste back to the phone through the USB when mounted as a disk drive, I have all the contacts and apps that I need saved but lost all of my calander details which for me include 6 months of booking and events that I use for my business, it will only restore from my last back up on the ROM manager. Is there a way to replace just the calander file, I'm not sure how to view it in the PC back up or even where it would be located.

View 8 Replies View RelatedI need to securely wipe any personal data on my phone and tablet.
On my Linux notebook I just zero the whole disk one or two times and reinstall the OS, with my Android devices it's a little bit more complicated.
Is there a way to securely wipe all my data, for example using fastboot?
Isn't there anything comparable to the good old
Code:
dd if=/dev/zero of=/dev/sdX
So that I can simply flash a new Android OS afterwards? Or at least for the data and cache partitions so that I just keep the OS
A method that definitely works is to just write a file to the data and cache partitions until there is no space left, but I wondered whether there is a "cleaner" solution?
I am looking for a lock screen app that will wipe the device of all data if the password is entered incorrectly after a set amount of times.
