Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

Good to know and I've observed that behavior. Unfortunately that doesn't help my use case. I'm trying to track down what's suckling up my battery so that I only get 3 hours of heavy use when I before I could get almost a full day when I used it as a WiFi only device.

Now before people jump on and say to get a new battery, note that I'm trying to track down what caused the battery drain when I still use it in WiFi hotspot and have 3g off. Also I need to know what causes the proportional difference given change X so telling me to shut off the phone off cell service is also not helpful.

Hence my need to wipe battery stats. When I could wipe battery stats, my steps were:

1) Make change

2) Wipe stats

3) Use phone

4) Go to battery settings to see breakdown of what used the battery

5) Go to 1 if not satisfied

Having to insert 1a) Charge up phone to 100% adds a ridiculously long time to the process. Plus according to the Google Engineer deleting data/system/batterystats.bin should work even if the option was taken out. As I've mentioned deleting the file does not work as expected.

Edited to clarify that I'm trying to track down what caused the change from when I used there same device and battery.

Any reason why my phone keeps saying "Insufficient storage space" when updating an app in the Google Store? I have plenty of space on my phone & memory card...

Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

How much space is plenty of space on your internal storage? I suspect there needs to be space available for some sort of copying. For example if I update an app but still have 24MB of internal storage left over, I'll still run into problems even if it's an SD card app.

I remember that on an 1500/1800mah battery, I got about 3-4 hours of screen on time with Gingerbread, and this figure is pretty consistent with other reports I've read on this board over the last 2.5 years.

Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

I don't have the screen shots to prove it but I used to be able to walk out of the library at 5pm and still have charge the next morning at 10am on CM 10. Now maybe my use has changed since at the time I had it on airplane mode the entire time because at the time it was a WiFi only device and an eBook reader with white on black. I'm pretty sure I was also able to sit in there library after a full charge and use it as a WiFi device for about 6 hours.

Even if my memory is completely mistaken, it still doesn't change that deleting /data/system/batterystats.bin supposedly deletes the information of how apps use battery. Yet doing so does not do that. Obviously there is a mechanism which the system does that when battery charges up to 100%.

Regardless of my motivation, this is a developers forum and sometimes I just want to learn more about how my system works. Sorry to hammer the point, but as coder and tech support (non-Android), I understand the motivation to question a user's assumptions and politely give them alternatives. I also understand that a lot of answers to battery questions miss the whole point that an apples to apples battery comparison doesn't depend on how old the battery is or system used.

Basically if use X1 produces delta B1/hr change in battery use and if use X2 produces delta B2/hr then if you want to compare use X1 with X2, the problem reduces to delta B2 - delta B1. It doesn't matter how much total charge the battery has or how quickly other people's phones discharge given their different uses and location. All you need to do is keep the phone and battery constant provided the time used is sufficiently small enough that you don't have to worry about equipment degradation.

You need to clear your cache. Easiest way is thru CWM. Its an annoying issue I run into all the time when updating large apps like chrome or most zynga apps
[Epic 4G Android Development] mordant23:
Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

That explains it. I've cleared specific app's caches in the Apps settings. There are also apps or features of apps that clear the cache for you. Makes it easier than using CWM.

Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

Another super easy way to clear app caches is through settings-storage. Just touch the cache percentage and it will give you the option to clear cache. Maybe not as thorough as CWM, but no special app or reboot.

Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

You'll probably never see this ever again so I figure I'll post some screen shots. While I would love to learn how to reset battery stats whenever I want regardless of charge, a good work around has been to let the battery deplete for 15 to 30 minutes while I use my phone, charge to 100%, then unplug charger. Repeat. Alternatively just let the the battery deplete while I use my phone until a set percentage 90 or 80% and then note how long it takes. It's not a perfect test because my tasks are different but the use cases are similar. I use my Epic as my primary computing device in Wi-Fi hotspots except for coding but I'm not a heavy phone user. My efforts paid off because not having a wallpaper (which produces a black background) and always using inverted option in the Browser really extends battery life. Next goal is to use inverted apps.

I think what happened to produce the weird results you'll see is that I forgot to manually turn off the GPS after I used Maps to get me to a comedy night to talk to the promoter to get a shout to perform at in a few weeks. Facebook used GPS for over four hours until I manually turned off GPS after I left the bar.

Edit: I don't know what happened to the inline pictures while I posted this. I ran into some sort of glitch. Guess the xda app couldn't handle the 61% battery use by Facebook!

Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

Yeah I think cm might be larger than stock roms, or the data partition is made smaller so leaves less room for apps. Back in the day there was a patch on the HTC Hero that let you configure partition sizes for cm7 so you could whittle the system partition to bare minimum and make the data partition larger. Haven't seen anything like that for our epics though. :(
[Epic 4G Android Development] jeffreyjicha:
Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

CM (particularly CM 9-10.1) have much larger system partitions than GB ROMs, but they also have larger data partitions as well. When ever I come across having low space, I just go through my apps and uninstall the ones I haven't used in a while.
[Epic 4G Android Development] VAnative21:
Yeah that's what I'm doing right now... thanks for the advice!

Oh OK... I didn't know that thanks for the information, I appreciate it!
[Epic 4G Android Development] propjockey:
Re: [ROM][OFFICIAL] CyanogenMod 10.1 Preview Builds for Samsung Epic 4G

Yep. In order for us to get CM9+ the devs needed to convert to an open source file system and increase the size of the system partition. In doing so, space was reallocated from data. And as was said above, I think there is more data kept on the data partition with the 4.0+ ROMs. As far as making more room on the system partition to shrink it's size, I think it's about as small as it can be. Try adding any file of moderate size to system, and you'll find there isn't any room. I believe they even had to make it slightly larger after 10 to allow for 10.1.

Here you are, a fresh build with the new Jellybean 4.2.2. That said, I don't know if there are any new bugs introduced by the new code changes.

- I have been using my BT headset for a few hours, doing my best to make it fail. So far it has been running very well, although I'm not going to declare it fixed yet. It's still early and I might just be getting lucky.

- I am not yet aware of any new gapps, so keep using the 4.2.1 gapps from goo. I did a dirty flash over my previous 4.2.1 build and haven't noticed any issues yet. YMMV.

Hi all -

Appreciate any advice on what I should do or not do to update my phone.

just fyi, dirty-flashing from

cm-10.1-20130120-EXPERIMENTAL-epicmtd.zip -> cm-10.1-20130215-EXPERIMENTAL-epicmtd.zip

where Link2SD had been installed did NOT go well.

the flash itself was fine, but the 'updating' of apps after flash kept quitting apps, with 'out of' or 'low on' memory messages.

after ~ 4-5 boot cycles, I was able to get to a Trebuchet desktop, only to find the sdcard was not mounted, or even recognized, at all.

did not manage to mount @adb, either.

resorted to a complete wipe + clean-flash.

reinstall of link2sd & manual script, then restore apps/date - NOT system apps - from TB, all's well again.

so far, the new 4.2.2 flash is smooth as silk. no restarts/gliteches/etc that i've found.
