ZeroLemon 9,000 mAh Extended Battery Review

[nuevosean]

That's his way of saying he doesn't know. Sadly it appears no one else does either. I asked about the reboot because it's alot easier to do that than pull the battery each time especially if it's in a case. Additionally if I have to pull the batterry after using 3000mah I might as well put in another 3000mah factory battery and charge the first one.

The question is this...when it reaches "0%" does the phone auto turn off or does it just KEEP showing 0%? I'm sure I could eventually come up with a tasker profile/task that would run on boot which could display the "real" remainder without a reboot if the phone will continue to run.

It shuts down. Then when I turn it back on its up to about 50%.

Well ask around

This is the appropriate thread. Someone will stop by n see.

Well from my LG g4 experience it just turn off and yes I waited 10min to turn back on but it only lasted 15min but yours may vary

You might see if a "soft reboot" works likewise..it's much faster to get you back up and running...you could even set an automated task in tasker or one of the free alternatives that would soft reboot the phone when the battery gets to 5% so it wouldn't do a "shutdown".

For the zerolemon if their 9000mah is accurate it should be around 66% when shutdown and restarted. If it's only 50% then it's not at what they are saying it's at...of course they would probably say it's user error for not fully draining and slow charging the battery 4 to 5 times initially but wasn't lithium batteries supposed to eliminate the "burn in" issues with batteries?

Yeah that's pretty much what I'm doing now. Just hoping for a kernel/root file based solution or something.

I'm sorry but a soft reset an't going to help. I've tried everything in the book. Unless y'all can't change the capacity then the App I posted is the only fix

It's not a fix to the (dys)functional problem is all. I know what you mean. We just want a seamless experience w/o reboots, is all. That tool won't do that. No big deal, skipper.

Basically I just wanna know where exactly the capacity is determined in the root file system for this particular phone, and if editing that (i AM rooted) will fix the issue.

Been batling with the zl 9000mah battery . i tried charging it thru external battery charger . universal charger m. And guess what im using the stock battery and no more drain or issues so far .. The battery reading seems accurate if using 3000mah ..

As for the extra juice .. Im shutting off the device the wobly case then the battery .. Then start again m. Irestarting wont give you extra juice .. U have to unplug the battery from the back that makes it so worst since the case is prone to wear and tear

Yeah, that's the thing. It's not reading accurately with the 9000mAh battery because while MOST phones read whatever battery is in there and at least try to adjust accordingly, apparently this function is blocked on the V10. This is why I'm looking for a solution to do it manually. It's not the biggest deal in the world to have to reboot to get that extra power, but it'd be nice if we didn't have to, is all...

Hope some one can help us with this.

Ok, limeuld, looks like I found the solution (for myself, anyway). Yesterday about noon after I bump charged it all the way to 100% (reading 100% when the phone is BOTH on AND off) I cleared my Dalvik/ART cache and regular cache in recovery. Since then, I haven't had my phone on the charger the entire night with moderate to heavy use and I still have 22% at the moment (6:20am (18hrs later)). If you're not rooted with a custom recovery, there are ways to clear that Dalvik/ART cache. Let me know if you need help with this.

Update: Phone shut off at 8:40am and I checked the power with the phone turned off and it was indeed at 0. Looks like this is a confirmed fix to our specific issue.

Update 2: if you pull the battery afterwards you'll have to do it all over again.

Phone is not rooted nor custom recovery . im on 6.0 hays


I saw online that if you factory reset your phone it will cleared ?

Whats with update 2 bro

Factory resetting will do it as well, but if you know adb, go into fastboot and enter these commands:

su system
cd data/dalvik-cache/
/data/dalvik-cache $ rm *
/data/dalvik-cache $ exit
/data $ exit

Then reboot.

As far as update 2, I pulled the battery just for testing and ended up back where i started. Doing the same process again seems to have fixed it though. Turning the phone off is ok, but pulling the battery seems to break it.

What about if you recharge it after it's gotten low...is it still accurate provided it's not pulled?

What actually happened to the battery? I have tested my TQTHL4500mah slim battery and my 6000mah and to pull the battery does nothing but drain the battery for 1% and I have a battery charger and with USB Charging I got far less SOT but with my battery charger I got better SOT so far as These Quick Charge Tech it's only ment for the original battery. I even tried charging overnight and still same issue. So charging with the battery charger is the way to go

If you read his post, he stated by wiping out the dalvik cache he was able to get the full length of time from the battery without having to pull it. As soon as the cache was rebuilt after a reboot the same issue came up until he again deleted the cache. If it can be recharged and drain as it should then the only thing that would have to be done is wipe out the dalvik cache on each boot.

Thsts boring. Just do as I did and buy the charger and batteries

Umm no... a simple init.d script can be setup to wipe the dalvik cache on boot automating the whole thing. You keep pulling and swapping batteries if you prefer.

 

[WAIDroid]

Well I do. Not that hard to do...

 

[limueld]

No updates yet . tsk 9 hours sot in zerolemon .? Data on then heavy usage games

 

[TheDaddyCat]

So tell me this.. what is the Maxx screen on time you guys have gotten on one full charge with this battery?
