Battery Feipusi 2300 mAh Li-ion / P930,LU6200,SU640

Battery 飞普斯 (Feipusi) 2300mAh Li-ion for P930/LU6200/SU640
Just bought one of these on chinese Taobao.com and it really improve batterylife! Also good quality, not crappy and without the feeling that it may blow up someday.
Good thing is, same size like original battery because i dont like the look and feel with the 3000+ mAh batteries.

After 3,5 hours of use (some Wifi/phonecalls) still on 100%!!! No way with stock LG battery... nice one.
Edit: 5,5 hours... still on 100%, more than weird but i like it!

That can't be possible. Reboot the phone and see if it shows you a true battery percentage.

I've read those are pretty good for use, typically better than stock batteries, but that they tend to drain a little more quickly when the phone's in standby than stock batteries. Regardless, I bought a couple. They're cheap enough, I'll give it a whirl =) worst case scenario, a couple extra backup batteries for me!

I thought so too, first guess was that i had to clean battery stats. After that it wasn't on 100%. But still at 89% now, after more than 7 hours with wifi on... movie on highest brightness and whatever.
Let's see if the performance will last, saw a lot of chinese products starting nice but in the end... :cyclops:

What rom and kernel are you running? What have you done to preserve battery life?

Have you actually put the battery through a few full charge-discharge cycles? Without putting it through a few days of use first, it is not really possible to tell how the battery performs compared to the stock battery.
It seems fishy that this battery is the same size as the stock 1800 mAh battery, but has a 30% increase in capacity...

I will try a few days and let you know. The battery weights more than the stock one. My wife's Lenovo phone have also 2300mAh tiny battery.
I guess the phone can't read the battery's information.

Interested in more in depth reviews!

been looking for something like this for a while. Should be great if you could give us a complete review & comparison. Thanks

I did not have much time the last days, here a short update.
Battery meter shows 100% for a long time, after some reboots it will go down to 90% but no change in battery meter if i dont do a reboot. Later the phone will shot down without any warning.
I will try to fully drain the battery and charge it in my phone with stock LG charger, see how this works out. I charged it with the 3rd party charger, that comes with the battery.
Also no success with battery calibration (because it won't charge if meter shows 100%) and clean battery stats in CWM.

Hi Cromson, can you test the battery calibration with Stock ICS, thanks!

To me, a battery that can't actually report its battery level (and has a questionable third party mAH claim) isn't worth ANY amount of money.
Just buy a second OEM BL-49KH battery and swap them out if you are concerned about extra bulk, and if you aren't get a Hyperion "3800" mAH battery.

Battery level is there, after some full cycle's (draining/loading) in the phone. Definitly better than stock battery, approx. 3-4 hours more time.

The fact that it cannot actually report battery level is highly suspicious. The Hyperion 3800mAh has no problems reporting accurate battery level.

So are there any other alternatives to fix the battery life? It's really horrible...what roms are you guys using?

I plan on buying this battery from ebay on Friday

I just bought this battery. I'll wipe the battery stats as soon as I get it and charge it to a 100%. How long did it take it to arrive for you? I live in the US

Battery seems to be draining slightly faster than stock for me... not sure why. On cm9 w/ ho!no! v5 kernel. The better feels a little better than the 1900mhz batteries from ebay i've tried. phone just sucks w/ battery life...

Woot woot! My battery just came in the mail today - Charging it to 100% as I type now

Good battery replacement

My battery is running out after 2 years and more usage. What is an excellent replacement for desire Z/G2 battery?
Thanks

Anker 1600 mAh. Have been using it over 6 months now. Easily keeps my phone up at least 30% more than stock battery.

I bought a HTC original battery from eBay for the Incredible S for about 8 EUR. It's the same battery as ours, only with more capacity, 1450mah.
I also had an old battery, at least two years old. The new one's performance is incredible, almost two days with medium usage. Using Gen.Y VisionX R3.

I plan on picking up a new battery soon, recently the phone has been randomly rebooting. I read this might be a battery issue, so a fresher, longer battery life can't hurt.

I've found that the problem with random reboots are the battery contacts. Try reinserting the battery a few times.

I'm using a Mugen 1800mAh, best money I ever spent on my DZ. Running a nice stable and optimized ROM I was getting over 40 hours battery life which was amazing with my usage patterns. It still fits into the phone using the standard rear cover also.
Link: http://www.ebay.com.au/itm/MUGEN-18...450941?pt=PDA_Accessories&hash=item5d3888d87d

I got myself an anker 1600 on eBay
Can't wait to try it. Hopefully this fixes my random rebooting. Can anyone report back if the new battery fixed this problem?
UPDATE: IT fixed my random rebooting! my phone works great now. no problems what so ever. best money i ever spent

Good to know, thanks for sharing!
There are so many crappy "high-capacity" batteries coming from china... We don't know who to trust.
Thanks!

Hey guys, just bought an Ankers 1600mAh battery, does anyone know a good procedure for replacing batteries? And I don't mean take the back off... :silly: Do you suggest I do a full charge, wipe battery stats, replace? What are your thoughts? Thanks very much

HERE ARE SOME GOOD TIPS
personally i charge full the first run (overnight) then reboot in the am and drain to around 10% reboot and charge full overnight and reboot in am. then use it like always.
this is just what i have done for years and many will tell you there is no need to train any lithium based batteries... but it works for me so this is how i do it
most will also say that wiping battery stats wont help as they are cleared on a reboot but i do find myself doing it anyway (i have lots of pointless habits i guess)

I run galilio evo4 2000 mah for more than a year.
I run a capacity test, I got around 1600 mah for both battery after about a year of use. Witch is very good.
I got 2 batteries and a charger for 20 $.
Do the rotation of oem and those galilio to keep them in shape.

Mass battery drain?

So I'm on 4.4.2 stock, Stock kernel, and I'm getting ridiculous battery drain. Any app I use, I will use for 5 minutes and lose 10% battery. Had 100 and then to 72 in a matter of 20ish minutes. And then as I'm typing this I plug it in and it jumps from 72 to 18?! Anyone know what the f is going on????

I had to same issue, I use this app on the play store called battery doctor (battery saver) its very well saves me battery,
Now there's a test you can do yourself to see if ur battery is bad or going back one is see if the little white sticker us still white if its pink it came into contact with water, another thing you can do is sit the batter flat on a table and spin it if it spins by itself( try on both sides) that means the battery is fattening up and needs to be replaced. Or if u want to you can take ur phone to sprint store and have them test the battery. You just say I need my battery tested I think it's bad. And they will do it for you I used to work for sprint. Now if u need another battery the stock battery is Samsung and you can get it cheap on Amazon.

Halp. I got a new battery, the anker 2200 mah, and I'm having issues again.. Charged all night, within 20 minutes of unplug I'm at 63 percent, then I plug back in to charge and I drop to 23???

It's definitely gotta be TouchWiz (if you're still using it). I have a backup of it via TWRP and I use it when I have ST network issues. When I flashed CM11 and spent a few nights charging and using it through the day, it got used to me using it. I don't know why, TouchWiz just has too much battery usage.

try doing a battery reset once you have the new battery in...

TouchWiz drained my battery so I could only get about 4 hours out of it. I have PacROM which is stripped down more than touchwiz+slim Gapps, and I (attempted to) enable battery tweaks but it didn't want to stay checked. I usually have my brightness down all the way and use Advanced Task Killer to kill my apps.
I remember when I used to use that on my LG Optimus S. Good days...

No Flash with low Battery

Hi,
Is it normal for HTC phones to block the camera flash when the Battery is low?
I've been out last night and had about 14% battery, when I wanted to take a picture I got this message.
Even deactivating battery safe mode didn't allow for flash

Yes, in the past under 15% no flash. It was tweaked to 5% before. I forget if its the app, framework, or kernel. I am sure it will get tweaked when devs get the phone and start hacking away.

My LG G4 also does the same thing. I'm pretty sure my M7 also prevented flash below 15%

Business as usual. Most phones do this. Be glad they do this.
At 15% or below, the voltage of the battery is really low and if you use flashlight, which uses a lot of power = voltage goes down rapidly. And your phone "dies" quickly.

I'm totally fine with my phone dying right after I take this picture! I just want to take this goddamn picture with a flash.

Well good luck charging your phone with non-removable battery if the voltage dips too low.
There's a reason for these limitations and you don't wanna discharge lithium ion batteries past a certain point.
And that's not something which is hard to do with lithium's, if the voltage actually goes too low, the charging circuitry won't necessarily "recognize" the battery at all and refuse to charge.
Maybe there's some amount of trickle charge present so if you keep the phone connected it might be able to revive the battery (bump the voltage high enough for the charge circuit to work)
Though the chances of this are relatively low because most charging circuits are waaaay smarter these days and if there's some amount of trickle charge present, the current is so low it might not have any effect on the voltage of the battery..
But if you end up in that kind of situation, there's already permanent damage done to the cell (battery) and it will affect the battery life negatively.
And I wouldn't necessarily even want to attempt to revive a lithium ion battery which is wrapped around aluminium....

At first I must say, I am jealous! How old is your phone now? . Saturn-Onlineshop in Gemany says the phone is available on Monday.
To the problem: I think we have to wait until root and custom roms are available..

While you're technically correct it doesn't matter at all.
Phones are idiot proof. If the battery reaches a critical low the phone will shut down.
I doubt that a flash would use so much energy that a battery at 15% would instantly die from it.
AFAIK voltage is pretty persistent until it reaches 5%
It's 3.7V right now at 18%, I'll take a look at 5% and below.
Edit: here it is.
Drops below 3.6V after 3%

I think 5% is a good threshold for blocking flash....15% was probably based on state of affairs 5 years ago. Its another case of software not getting tuned to the times.

So you say now....until your phone dies because of constant snapping, and it doesn't have time to actually process the photos. While it may not take it very long to process the photos, a sudden death might result in a loss of quality.

What is YOUR battery wear!?

So accubattery is telling me my battery is at 90% health? 4500MAH instead of the 5,000 its supposed to have. Like do these phones have weak ass batteries ? Ever since the note 7 Samsung had made extraordinary batteries that age 1% in 4 years

The batteries on these phones are fine. Mine frome new said something similar to yours, using the same app, which I'm still using.
I regularly get 8 - 9 hours screen on time. With 34 hours sleep. The battery on the Mate 20X is stellar.
If you're not happy buy a Samsung.
The app calculations may be wrong, and you can set the design capacity yourself. Also I think it establishes over a few charges the capacity.

I don't pay any attention to accubattery as in the past it has been anything but accurate.

Accbattery says 96 percent here. 6 months of pretty heavy use and always fast charge or supercharge.

WOW

I've got the phone for just a month. But it was used since February so its already more than 3 months old.
I try to keep the battery level around 50 to 70%.
I haven't been in a situation where I have to charge it to 100% yet. But I plan to do it only when I need to because I know it will keep the battery healthy for a longer time.
I am using two SIM cards the whole time.
Since I have the phone I haven't conected it to any WiFi network and I have cell data on 100% of the time.
Bluetooth on 80% since I wake up until I go to bed.
Never used power saving mode since the second day I have the phone and realised this is not the Samsung I'm used to work with.
Let me know if you can't see the screenshots

That isnt accurate, i did the test after 6, 7 days after buying the phone (not mate 20x) and it said -95% wear... That is impossible .
