[Q] Battery Life and 4200mAh Replaceable Battery

Hey guys, I just wanted to check if my battery life is abnormal or not. During normal usage, it's a bit hard for me to compare because I'm tending to use this phone a lot more than my previous one (Xperia Z1 Compact) but overnight, it would tend to lose at least 7-8%. Last night, I decided to try disabling auto-sync, put it on Power Saving and see what would happen (as well as closed all my apps through the regular task manager) and it dropped a whopping from 45% to 31%! Don't know how that happened.
When I go into the Power menu, I can see that Android System used 13%, Android OS and Screen used 10% each, Google Play Services used 9% and a few other apps and services used 4% or less. I got my Note Edge in Australia and is currently using it in the U.K but it's an international variant (SM-N915G) and is compatible with my current carrier (O2). I'm running stock 5.0.1 rooted. Do you guys think it's normal?
Another question regarding the battery: I have never owned a smartphone before that allowed me to switch batteries so I was wondering, would something like this or this be trustworthy? They seem really cheap and the capacity is 4200mAh whereas the stock battery is only 3000mAh. From your experience buying replaceable batteries, is it safe to use something like this (not to mention, they says they're compatible with the N9150 but didn't mention the N915G)? Thanks a lot in advance!

A lot of folks have had similar issues with lollipop. Backup all your data and do and full reset. Seems to sort out the battery drain issues
Good luck

Thanks a lot. Just a quick noobie question, should I just backup with Titanium and then do a reset from inside the OS or should I do it through CWM (I already have a recent enough nand backup). Cheers!

I have had horrid battery life since lollipop upgrade. I want to go back to kit kat so bad. Primarily because of the battery and because notifications appear as overlays in some apps now instead of on the edge. The phone also is less responsive. I kick myself every day for upgrading.
Side note, are the batteries listed above supposed to actually fit inside the phone with no physical distortion?

I haven't had any major issues since upgrading to Lollipop, I was just hoping to squeeze a bit more out of the battery life. As for responsiveness, I'd say it's about the same, if not slightly better. You sound like you might also do with a factory reset. I just want to know if the factory reset option in the settings would do the job or if I should do it from the recovery.
As for the above batteries, I would imagine that they should fit perfectly since they were designed for the Note Edge but since I have had no experience with replaceable batteries, I would like to hear some confirmation.

I have mine on power saving mode and screen brightness on 43%. I get two full days usage so I only charge it once every two days.

In those 2 days, could you take a look and let me know how long your screen was on for?

I had a battery from the same manufacturer as your first link for a s2, it was apparently bigger in capacity, but drained faster than the stock battery and swelled after two weeks to the point that the rear cover wouldnt close fully.
Id steer clear if i was you.

Yeah, that was my concern. The only time I had a higher capacity battery fit snugly into a phone and work as intended was when I had my htc sensation. Anker made a higher mA battery that really worked. Everything now seems to be a sham. I will avoid it.

You can't fit more capacity of battery in the same size more than it's done by Samsung, otherwise they would do it. These are just fake numbers, I'm sure they're even less than the 3,000 made by Samsung.
As for the resetting your phone, settings option pretty much does the job.

Couldn't find replacement battery and back cover

It seem like there is no way to buy a replacement battery for nexus 9 or the back cover. Is there any source for the purchasing？

http://bfy.tw/3RGR
http://www.etradesupply.com/htc/tablet/htc-google-nexus-9.html
https://www.ifixit.com/Store/Parts/HTC-Nexus-9

At both sites the replacement battery is out of stock. My battery has started acting very strange (tablet totally turns off around 20%, then when i plug it in battery is 100% dead, needs 15 minutes charging just to start up again).
I did quite a bit of googling but didn't find anything.

If anybody is still searching (or has given up already): I just got a new battery from here: http://bigupgadgets.com/battery-35h00218-00m-b0p82100-for-htc-flounder.html. You may find it from other vendors if you search for "35H00218-00M".
The printing on the back looks different from my old battery - looks like this is indeed a new part, rather than a refurbished/replacement HTC battery. It fit perfectly, and charged fine. I just installed it yesterday, so I can't yet say how well it performs long term.

So how did it turn out? My Nexus 9 is going to become sort of a lab rat for full-scale linux development on the device so I'm considering replacing the dying battery as well. I could get the aforementioned battery for around 30€. If the battery works without blowing up and is the advertised capacity, that is.

It worked well, fewer slowdowns and crashes. That may be in part also because I fixed the location of the copper plate/heat sink that had been placed under the original battery (leading the heat into the device) to where it was supposed to be. Some problems that may be more related to the chip/RAM/64bit choice persisted (browser is still super slow with just a few tabs open). Not using it much these days except for ebooks, Hoopla, etc. When I don't use it for a while, I turn of the Wifi and the charge holds for many days. Good luck with your Linux endeavors.

Well all the other malfunctions are definitely NOT related to the battery, except if the old one maybe started to lack in persistent current delivery (which would cause the sudden shutoff - my Nextbit Robin had it as well and it would behave as if the battery wasn't designed to power the chipset, crashing at 70% charge). If something in the power delivery goes wonky then maybe that also messed up some memory addresses and CPU calculations.
But enough being a smartass - if the battery does hold up without life-threatening malfunctions then it might be a good option?

What I was trying to share is that the new battery (and its proper placement) fixed a couple of things for me that I hadn't expected to be related to the battery. So I got actually way more than just increased battery life. With some non-original batteries (e.g. for cameras) you see that the copies are definitely inferior to the original. This one was as good or better.
Of course that was two years ago - production standards may have changed, or you may get a battery that's been sitting around for the last two years (what would that do to a battery? - I have no idea). Mine's still working well after this time. I would definitely go for it, but I'd try to find a vendor where I can send it back if for some reason it's not working as advertised. I haven't heard of any of these batteries exploding, and really would not worry about it. Hope that helps.

LG G5 Extended batteries from third party sources?

Alright. Just like what happens with many smartphones, third party sources have started releasing batteries with a little more juice than the Original LG Batteries of 2800mAh. I have to admit it, i was kind of counting on it because it happens a lot of time. But how reliable could they be? Would NFC work with them? Will it make our phone explode? From 2800mAh to 3250mAh is 450 more juice to drain. Has someone tested it? I've posted the link and a couple of pictures.

Can you please also try the NFC feature if you have another phone with NFC capability? And also, whether the SOT improves or if it remains the same. and finally, in comparison to the other battery, how long does the phone last , based on your average usage (say: wifi on/off, usual brightness or auto brightness, etc. ) Let us know. Thanks

On my Thread I found one that has 3600mah found at AliExpress

I have tested for two day and although I haven't gotten any numbers to prove it...the battery works great. It does last longer with the same usage...but I wouldn't say that the difference is huge but it does have a little more endurance. I'd say that if you are looking for an extra battery...this is not a bad choice especially just to keep as a spare. Everything works fine as well.
Also...it may take a few cycles to get the battery calibrated...my first discharge I was disappointed because it dad extremely fast but after letting it run down and charging it a few times it seems to last a little longer than stock. I'll leave the battery in for a while and if I get time to collect screen on before I charge it I will.

I think one would see a real difference if it had 900mah ane up more than usual. I was kind of expecting for that though. Hahaha. But i have the feeling they will release an eveb bigger one. Something like 4000mAh+ but you have provided us with great detail. Thank you. If you have the SOT in the future feel free to provide if

I doubt we will see anything much larger in the same size. Batteries have limited capacity/cm3, and LG, being one of the best and largest battery manufacturer, maxed out on that value. The problem here is the physical size of the battery cell...

They managed to do that by replacing the back cover with their own "case", including an extra-size cell. The G5's different battery removal mechanics make it a lot less viable option, especially adding the bottom module (which houses not just the USB connector, but speakers, microphone, and some antennas) as a cost.
My original comment was directed at the allegedly 3200/3250mAh cells popping up for 5-10$ a piece. There's a reason why official LG cells are 25$, and these after-market ones cost less than half of that. Sure, LG needs to cover the development costs, but I'm pretty sure the after-market ones are so cheap mainly because of corner cutting. And that comes with extended hazard. But if you feel like ruining your 600$+ phone because you went cheap and paid 10$ instead of 25$ for a battery... It's your call.

They could create a module similar to the Cam+ that has an 'extra' battery in it. Maybe slimmer but further up the case.

Check out this thread I did for the Sensation (ages ago). It's not relevant to this phone, other than to say that you'll recognize some of the labels:
http://forum.xda-developers.com/showthread.php?t=1753726
The TLDR: Actual mAh was was tested reliably (external discharge, outside of the phone) and batteries with the same label style as the two linked in the OP actually had roughly 30% and 50% of their stated capacity, and much less than stock.
I've got a G5 coming this week. I wouldn't be against doing another thread like the one I did in 2012 on the Sensation, if there's demand.

I have this one coming, so i will let you all know what i find. There seems to be mixed reviews, and even my Stock Battery had to be calibrated up/down charge for 3-5 times before i had good life.

The mixed reviews are in part my fault. I'm one of the reviewers with that battery and for some reason Amazon will not post my updated review, I've tried 3 different occasions to post follow ups but they won't post.
What I learned with that battery is it works, only it does give me the invalid battery message and the phone shuts off but only if I reboot the phone at 100% battery life, upon booting the phone reports 50% charge and shuts off. You have to restart it a couple times until it's used a percentage or 2, then it boots fine. I emailed the seller about it and they responded with the cells are tested and they only use quality parts, they sent me another battery but that one does the same as the original. With the issue with the note 7 and other phones/chargers I stopped using the battery. It might be perfectly safe but I can't determine that and the risk is not one I am willing to wait and see. Here's a link to another topic here on XDA where I responded about this battery.

So, after the first full charge and discharge to 11%, I'm getting very good times better than stock. This will probably increase with a few more charging cycles. My opinion is this battery is definitely more mA. I will review more when later.

Kompson vs Stock Battery

So guys, celebrating or Forum acquisition.
Let's talk about one of the biggest issues that a huge part of S3 users, that acquired their phones last year had. The battery drop.
It weirdly started for some after the Lollipop upgrade, with a 15 or 20 sudden drop, 1, 2, 3 seconds and you phone turns off!
Firstly we all thought this was a software issue, but after countless work and updates on this part and no fix for it, we started to think that problem was not a software one but with batteries itself.
The cause will remain a mystery. A defective lot? A issue that was ignited by LP? And proof of batteries defect, the drops gets worse with time. 20, 30, 40% drop to zero, batteries getting inflacted watch out if you have this issue!
Fortunately this seems to be fixed in newest batteries, that are sold on main stores, if you're ordering a original one get from main stores, Aliexpress stores are just selling fake ones by my investigations.
Luckily we found at Aliexpress this Kompson battery. At first sight it looked like a big scam, promising capacity for a not so popular phone? Definitely could look like a scam. But then a courageous buyer bought one and not only got great capacity or duration, as got the drop issue aliviated.
My case, after a whole year with two original batteries. They started to suffer huge drops from 50% in the last 6 months, with max of 2:30 SOT. One got inflated, they badly lasted me more than a . Yesterday finally got my Kompson and my issue meet a end. No drop, maybe at 5%, 3% I got a drop to 1% then it last some time more and turns off.
This topic is to inform people with the Drop issue, as well as letting your experience with new, old stock batteries or Kompson. In order to inform and help people with this freaking issue.

I only got one battery with my device, so the moment I started to notice these strange drops, plus none of the "rescue" solutions such as battery calibration (rooted), didn't do anything, I search AliXpress, and bought one KonPson with any risk...
Since March 29th that I am using it, the phone works also with 0%!!! No crazy drops, no suddden 50%...
The load discharges slow an normaly.
TapaTalk and JiaYu S3 with Android MM!

Battery calibration isnt quick process to get rid off drops. What You need to do is stay with ONE rom longer! Do a calibration at 100%. Restart the phone. Than three-five times fully discharge battery (with normal use) and charge it to 100% its times. It take week or so. I have konspon and orginal battery and I dont have any drops - no matter which battery I use. I've made flashable batterystats file (from my own file after a week or so) and when I need to test new rom and return to mine testes I do flash batterystats.bin file via recovery and thats all.

I had two defective batteries, no way a calibration would save them from 50% drops.

Just swapped in my Kompson that I purchased a few months ago as a spare as I was experiencing a 10% drop. From my experience it was definitely battery degradation as it started fine and eventually worked up to 5% then 10% while the Kompson goes all the way down to 0%. It will be interesting to see if the Kompson does the same in such a short period as then it might be the device causing degredation rather than poorly made batteries.

One more question. Is it the store you bought from (BouBoo International trade co., LTD)?
https://www.aliexpress.com/item/kon...ttery-free-shipping-Tracking/32360303710.html

I have 5 batteries and a pair of external chargers. One of the 5 is a Kompson. The differences are not abysmal but their performance is better.

Hi,
Where could I buy legit battery (stock or konpson) for Jiayu S3 Advance?

I have this same exact battery, I was the first one to get my hands on in our group and its so good that my facebook friends started to try buying it from me. So I sold it to one of them after I sold my jiayu s3 to get an iPhone.
Now that I just went back from an iPhone 2 months ago into another Jiayu S3 unit, I have to buy another Konpson battery for the same reason why my friends wants my Konpson so bad. LOL
Bye bye batt drops, hello my dear konpson
If you're gonna get one, just ignore what the capacity says. As long as it says Konpson for jiayu s3, you're all good. Those capacity are just labels anyway, in reality its the same capacity to the stock battery, just more efficient as to why it works and performs better than the stock battery despite having the same capacity.

kompson batteries no longer exist. now they are ones called "losoncoer" i think is the same factory (very similar sticker)
soon it will arrive and i will try it

I'm not a heavy user, no gaming, occasionally stream netflix. Recently I have streamed netflix onto the tv with a cable. The cable is supposed to charge the phone, but it doesn't, so after a couple hours the phone is down to about 50%
So I went to pull the battery thinking the system needed a recalibration.
The battery was bulging (gases building up). Not good. I don't know if this was an isolated issue or as these phones get older, there is a flaw in some of the batteries.
The battery was the original. The phones manufacture date is 10/2016.
As a side note, the phone stores don't carry batteries. Batteries Plus has to order it $39.99. I ordered a couple OEM LG batteries off ebay for about $12 apiece. Now I get to go a week or so without a phone. It might be a good idea to get a spare and check your battery periodically. Better safe than sorry.
Cheers!

You should have called up LG. I would not trust any 3rd party or eBay.

Bought Aexpower X2 and a charger on Amazon for about $25 been solid for 6 months

All battery's will eventually fail, it's inherant in the current design iteration of lithium ion battery's, how long and how bad can vary, but a lithium battery that has consistent charge/discharge cycles daily will last around 8-16 months on average, doesn't matter what brand or size, it's just how there currently desgined, wait a few years till we have lithium-glass or lithium-plastic battery's then this will be a thing of the past...

Most every phone I have had I owned for 2 years. This is the first one to have a problem. Thank goodness it is removable.
Also, my dad (85 yrs old) had a Moto g4 he wasn't using. He switched to android because I did, but screwed the phone up with really crappy apps. I told him I would set it up for him, but he didn't listen. So he went back to ios. I had to do a factory reset of the phone to get rid of all the crap. Got it set up right and it's not that bad a phone (might even root it). Removable back and battery, SD card. but no IR Blaster. It was unlocked so my tmo sim worked right away. At least I have a phone for the next week while I wait for the new batteries to show up.
I'll be keeping a close eye on the new batteries. I hope no one else has this problem. Very dangerous. The case I had it in concealed the problem. When I took the case off, the back plate fell right off. It had already been pushed of by the expanding battery, but the case kept it from being noticeable.
Cheers!

I have 3 LG V20s and I have bought extra batteries for all of them but have never encountered your issue. Could it be that your custom ROM may have something to do with it?

I don't think so. I've been using the same rom and kernel for about a year. Hopefully it was just an isolated case.

Strange that you should post this. I too have just run into this. I normally get about 1 1/2~2 yrs out of a battery on my smartphone, however on my LG V20 that I got in Nov '17 it just started doing the exact same thing. I'm fairly experienced so I was trying to isolate if anything untoward was going on software wise. After nothing really was attributable to the loss I decided to examine the battery and bingo just like you the battery is quite swollen. I'm hoping that the new "supposed oem" battery that I ordered last week (should show up by end of the week) lasts longer than the oem battery that shipped with the phone.

I am also having bloating batteries. One is the original oem and the other is aftermarket Hyperion. Both are about a year old. I wonder if quick charge might play a factor as I use it all the time.
