I tested a VHBW replacement battery and that one that I got is not really good.

I discharged the battery two times until phone goes off and then recharged it while phone was off with an usb current tester.

It only loads 2130 mAh..and that for a battery that should have 3100 mAh - that is a joke!

My about 2 years old original battery still have 2600 mAh - a lot more then that VHBW battery has new
[ONE Accessories] aplomb:
Hi all,

My phone keeps restarting and I comprehended after much articles, forums and videos that it is an hardware issue. I have to change the battery but was disappointed when I came to know that original batteries are not available anymore.

Still I took a chance and contacted OPO service center (and I am happy I did that..!). OP has not yet pulled the plug on OPO. They said batteries are not available in service centers at the moment, but if u pay an advance they can order it for you, post which u will be contacted to replace it. Though the whole process might take another 10-15 days. The cost would be INR 1600/- for battery and INR 400/- for services (i.e. replacing the battery). All this are excluding taxes, I suppose.

So if you are in India and specifically in Mumbai, then maybe you can try it out. I will be heading their in couple of days. Will update on my experience shortly. Adios..!
[ONE Accessories] Messatsu:
Can you please update on how much it shows on AccuBattery now?

I think the next I'll test ist this one:

https://www.aliexpress.com/item/100...lgo_pvid=0e41642e-207b-4c05-aa0b-be052a81b4b7

Most reviews are good and charged up to 3000mAh+.

But I think you need luck to get a good battery
[ONE Accessories] evronetwork:
This EACHTEK battery currently holds about 2.300mAh according to accubattery hahaha, I'll test it properly with my USB Meter to have a precise result

P.S. This is about 2, 2.5 weeks after replacing (at least I didn't pay for it, got my money back - he did scam me a bit(giving me 2.5e less due to paypal fees but I did leave him additional feedback saying about the backmail and the shortage of money))
[ONE Accessories] catxda:
Sorry for late answer.
[ONE Accessories] catxda:
But with external measurement device ( USB tester) and phone off from 1 - 100%
[ONE Accessories] evronetwork:
You had the phone turned off(deplete the battery to (!)) and then connect it to the usb meter without turning the phone on? - if yes that's the correct way :D
[ONE Accessories] catxda:
Yes phone was off 1% then connect to USB meter and keep it off till 100 % battery charge .

The issue is that difference between readings 2909 mah in accubattery and 2490 mah with USB tester !!!

I think is to big , maybe the USB meter is not accurate !!!
[ONE Accessories] Messatsu:
Indeed it's wierd...thanks for the update!

PS : It seems that the item isn't selt anymore with your previous ebay link ?
[ONE Accessories] Mr.Ak:
Usually, USB tester is known to be more accurate.
[ONE Accessories] eiwarmer:
Did you clear the cache and date of the app itself after you replaced the battery?
[ONE Accessories] evronetwork:
No, try to see a (!) and then shut off due to low power, try to turn it on and it should even pass the boot logo :p

USB Meters in general are way more accurate due to the fact the phone is turned off and doesn't consume power

-------------------------------------------------

Btw guys did you try this one? http://www.akkushop.de/de/akku-passend-fuer-den-oneplus-one-akku-a0001-one-blp571-akku/ ...Akku battery for our phone, if it's from Akku(a German company) it should be good(better than most at least)
[ONE Accessories] evronetwork:
If this is true I can kang the EACHTEK battery which is a confirmed low capacity battery and currently ~2.300mAh(with accubattery, after 1.5 week of usage) - It was less than 2.600mAh(first charge with usb meter)

I don't want to test with usb meter again, if I do and see around 2.000mAh I'll get quite mad :P

So can anyone confirm the dimension of ZTE Blade X3 battery compared to our battery? ...if it's the same, it would be a nice KANG :p ..I mean my hands are good, I've done weirder things than this, I just need to know if it fits, if it doesn't fit at all I don't want to waste time and money :D

P.S. Getting 3.500mAh real capacity would be amazing ..but I need to know more about dimensions and complications due to that :D if it's 4ah even better but surely a 4ah battery won't be 2.5ah or less

EDIT: Someone did it, it fits ...DAMN this should be the best alternative to battery replacement even if the X3 batteries are a bit old - https://www.youtube.com/watch?v=g7pWYCnmNBI

...trying to find a recent date battery to do the mod, I'll test today the EACHTEK battery with my USB meter from 0-100% to check it's state(I calculate around 2000-2200mAh at best after ~1.5 week of usage(useless if you ask me)), then do a few rounds with the original and finally order the ZTE battery(until then I'll have answers from 2 sellers I've asked) - better than 3.1Ah? damn that would be amazing, if it's near 4Ah it would be an WoW battery life - although the charging time would be more obviously

EDIT(07-10-17): Talked with the guy who did the mod, he wants to see my results too :P ..oh well I'll order soon(Mon/Tue I'l place the order - one seller replied waiting the second answer) the battery and do the mod(although ~1 month waiting due to China shipping). I'll upload a video about this too - You'll have a chance to see my custom heatsink too :P - I did record this too but had issues with the sd card back then so the video has tons of artifacts(can't upload that anywhere).

I did record changing the battery(EACHTEK) and making a custom heatsink step by step ...not as a guide but as of what I can do to help my phone but SD f me up ...I was really mad with the result but I can't do anything, many artifacts and green pixels everywhere hahah(I'll edit this to post a picture of it - I can extract a single picture out of "that")
[ONE Accessories] capdcanoa:
So to summarize, there is no good alternative to OPO battery....It's a disaster
[ONE Accessories] mat738:
After a week of this new battery use I can tell you my opinion: it took me 2-3 charges, but I finally reached the 4 hours of SOT that I was having when the original OPO battery was in good shape (changed it with 2500 mah max and 3 hour of sot according to accubattery).

There are a couple of downsides tough: number one there's no temperature sensor (stuck at 26.3 C), number two I think that accubattery is giving me a wrong reading, because when fully charged it showed me an estimated capacity of around 2500mah max (like the original one) while I have way more sot. I'm a little bit confused, so I uninstalled accubattery and I'm testing it on my real needs of daily use. I think I will give another chance to accubattery after some weeks of work.
[ONE Accessories] Syaani:
I have that battery too and after 11 sessions of charging Accubattery told me it has approximately 2900mAh. I ordered usb tester so I will get better statistics later. But well my old battery was only 2000mAh according to Accubattery app. This is far better than original one.
[ONE Accessories] evronetwork:
As said the best replace is from the ZTE blade x3

Tried to talk to a bunch of ebay sellers but all of them didn't reply, only aliexpress sellers did reply ...damn, I'll order it from aliexpress, damn... oh well it's for a good cause :P

So you'll hear from me in 1 month or so :p
[ONE Accessories] mat738:
Antoher downside that I forgot to mention before is that the flat cable didn't fit perfectly, so I had to stretch it a little in order to properly connect it.
[ONE Accessories] Syaani:
Okay, I didn't experience any issues with the cable.

Could you please link to where you ordered your battery from? I think I'm also going to try this :)
[ONE Accessories] brainvision:
It would be nice to change the battery with the ZTE one but the process is hard and dangerous and it needs two battery as I read: the ZTE one and another with similar connector of the OnePlus one (I would never use the original one just in case)..

So I'm not sure it's a good idea..
[ONE Accessories] evronetwork:
still in the talks ...seems sellers are not very good at talking, from ebay zero replies, from aliexpress 1 seller did reply and I'm not feeling good with him(barely speaks English)

Trying to find the latest manufacture date on a battery that I'll order not e.g. Jan 2015 :P
[ONE Accessories] AZGeek:
Have you tested the battery from AliExpress, and if you have what results can you share?
[ONE Accessories] Berth666:
I've ordered the battery but didn't received it till now.

But I'll post my experiences with it here when I received it.
[ONE Accessories] evronetwork:
Just place an order of this : https://www.aliexpress.com/item/3-8...19T-Blade-X3-D2-A452-Battery/32809338835.html

I'll use the BMS of the EACHTEK battery I currently use and make the mod, the battery would have a date of "2016-09-01" as the seller promised or newer. To make it clear it's 01 Sep 2016(so it's recent), it would be sweet to have more juice than original stock - Sure it requires some effort but for me it's nothing, I fix tablet/phones etc so it would be fun to do :P

P.S. I already have a custom heatsink solution to my phone, if I have time I'll make a video about the battery - but expect ~1 month after this message
[ONE Accessories] young-ster:
Looking forward to this, replacement "oem" has been lacking in every way
[ONE Accessories] twowheeler:
Does the temperature reading work on this one? I've tried two replacement ones, and both just stick to one temp (or go between 26.1 and 26.8). Currently have the original battery back, and that does correctly show it.

How's your battery now?
[ONE Accessories] evronetwork:
The EACHTEK battery is referred as 2.300mAh from the app ..I'm afraid to measure it with my usb tester because it should be close to 2.000mAh and it's not even

The "OEM" batteries have either a thin layer of plastic and are less mAh or bad quality and after a month or so(so as in my case with EACHTEK) they have quite some less capacity compared to the first/second charges

4.000 normal capacity? even if it's 1 year old and have 3.500mAh real it's still plenty and way more than the original capacity, I don't use my phone much(most of the time) so charges with original battery and COS was like 1 per 3 days, before changing my battery it was 1 per day ..now it's 1 per day for sure and sometimes 2 per day!! and I don't even play with my phone!!

If I go back to 1 per 3 days or 1 per 4 due to the extended capacity I'd be thrilled, if it's near 4.000mAh then I might have a full week with a single charge ahahahahah. Surely with heavy use you'll see need to charge it once per day but the SOT would be increased to an incredible degree
[ONE Accessories] young-ster:
The only reason why I even changed my battery was because the original has swelled or bloat and I was afraid it may get worst and worst and pop... all these fake oem ebay ones show 2300 - 2400 and I am like charging 2 - 3 times a day ... sadly
[ONE Accessories] twowheeler:
Has anyone had the problem when the percentage wasn't accurate? Like going from 80 to 85% after a reboot. My phone switched off (percentage was 0) but upon connecting the charger it went to 16%. I could then boot it up without the charger and deplete it to 0% percent again. Phone would turn off, but have 5%left on boot. This went on for a few times.

Does this mean it just needed calibration or is that battery broken?
[ONE Accessories] nitrobg:
I'm skeptical about the real capacity of the 4000mAh battery, even if it is for another device. If most batteries from China are either lower capacity or go bad within few weeks/months - it would not be limited only to OPO but extend to other phones as well.

You can't just pack more juice into the same physical dimensions as the original battery, keep that in mind.
[ONE Accessories] fuchrist:
The temperature sensor does not work and I'm afraid that I can't give an appropriate answer regarding the battery status. I flashed a new OS two days ago and didn't check the status for quite a while. After two loading cycles it says 90 %, which is sort of worrying though. I'll keep you updated in a week. Remind me if I forget to write a reply here.
[ONE Accessories] evronetwork:
Mine isn't swelled or anything but can charge up to 2.600-2.700 which isn't great and also if less than 10% it might shut off(so if battery less than 10% it might turn off going to 0% ...so 9%? it might shut off, 8% the same etc ..it's not reliable if 10% or less)

Well there's plenty of space around the battery, also if it's a tad thicker 1mm for example ..it's a big surface so capacity can be increased big time. The only thing I'm skeptical is about the longevity of the battery in other words. The EACHTEK I'm currenty having went from ~2.600 to 2.300 in about a month(damn!)

P.S. If it's an original ZTE battery as seller claim I don't care about the longevity of the battery. ZTE is not a fjasdidsaj company, sure it's not samsung(exploding batteries), lg, nokia, google ...but still if it's original it should last as good as our original battery. So 3 years with 4.000mAh or close? I'd be thrilled!
[ONE Accessories] OpIcarus:
Best link to buy the battery in this moment? Ty
[ONE Accessories] eiwarmer:
None at the moment. Everybody's still hitting and missing atm
[ONE Accessories] evronetwork:
I've mention my last try ...when I get the battery I'll have actual results with external usb meter so the results would be accurate, if want to be sure 100% that my work is done properly and the battery is as it's suppose to be ..wait another month to see if the real capacity is down or about the same

P.S. Currently trying to use the last 7% of the battery(EACHTEK ..change it about 1 month ago) to check the results with my usb external tester ...I expect about 2.200mAh real capacity(app says 2.300-2.400 nowadays) where it was 2.600mAh a month ago(new) - Still this BMS of the battery would be great for the ZTE's battery and I got about 80% of the money back(seller of the EACHTEK battery didn't refund me but choose to send money via paypal but as goods so the fee reduced the price so I got less - after that he didn't actually correct this but my additional feedback was "good" ;) )

---------- Post added at 02:37 PM ---------- Previous post was at 02:25 PM ----------

probably battery is broken or it's BMS anyway(if it's an aftermarket) ..BMS, Battery Management System aka the chip of the battery responsible to protect from overcharging, overdischarging, temperature sensor and charging current control - Also the BMS should be responsible to check and report the percentage(so most of the times the real problem is the BMS and not the cell itself)

P.S. Most laptop batteries are useless due to bad BMS and not cell degradation
[ONE Accessories] twowheeler:
Thanks, I think you're right. The percentage just kept changing, so i'm going to return that one. Have just replaced it with the original again and that one works like it should right away.

Judging by the bad quality of most replacements most of us are just better of sticking with the original. Sure some replacement batteries give us some capacity improvement, but it seems like they deteriorate quite fast.
[ONE Accessories] evronetwork:
Nah, no point in taking it appart to change the battery, I can deal with the low power for a month, also it would also impress me going from around 2.400mAh to 4.000 or so

Just tested the EACHTEK battery 0-100(phone shut off at 0% and tried to turn it on 3 times ...then charge it while it was off measuring the power it's getting from my usb tester)

This is the result (it had 2.600mAh a month ago) ..expected around 2.200 but it's more, I'm impressed :P

Hey I was just wondering weather your phone is working ok or not and did you check battery after some use if it has swollen or became tight in battery place? How was the size its compared to original after tweaking? I know it's a lot of questions, but would love to know the results. (P.S. I am just afraid that phone will explode lol.)
[ONE Accessories] evronetwork:
It's my only phone so yes it's working, battery is NOT swollen or tight BUT I charge it daily and in the past with my usage it lasted 1.5-3 days(never a single day unless I didn't leave it from my hands)

P.S. Now 1 day is normal and sometimes twice per day with my regular average usage(I don't play games or surfing the net - or rarely about the net) ...imagine that :P

[MENTION=4245550]twowheeler[/MENTION]

Accubattery still claims that the battery only has 90 % of the capacity that was originally promised. Since the value was ~ 97 % in the beginning, it seems like the battery deteriorates rather quickly.

Just letting anyone from India know that OnePlus does provide original battery replacement through their service centres. I got mine replaced today. Took about two weeks & cost was ₹1500(about $23).

They kept the phone with them for 2 weeks? Or we can go back with the phone 2 weeks later?

Please give me the exact address of the service center. I'll try through a friend. Also how's the battery performance after replacement. Any dents or something on the phone after the replacement. Hope it was a professional service. Awaiting your reply. Thanks again.

Hey, very interesting. I though genuine battery replacements were more costly but maybe they changed their prices. I'm just wondering, how did you contact them? Thanks!

I just went back to Eachtek battery because it's the only one that gives me good reading of the percentage.

It shuts off at 0% and so far no other non original battery has been able to do it, even after trying different calibration methods.
[ONE Accessories] unyk13:
You will have to submit your phone, so, better carry a spare one. You can find the address on the oneplus site. It's the only service centre in Cochin. I have attached screenshots of battery as well as the service record. They were very professional. I didn't notice any scratches or dents. Hope this helps.

P.S: I forgot to mention that I had paid an advance of Rs.250 at the time of submission. Please add it to the total cost.

[ONE Accessories] VISHAL4U2:
can anyone tell me which is the best and quick charger for our OPO in india ?

BTW i live in bengaluru, go my original charged damaged. want to buy a new charger but confused.

Did a lotta research and found that any charger with output of 2A would do the job. But i have observed that when i charge with moto turbo charger and xiaomi charger my phone got charged quickly. I have done enough reasearch on this and found that using any charger above 2A output wont damage the device (or battery) and would charge quickly. Although OPO is on Snapdragon 801 chipset which supports quickcharge 2.0 but an additional hardware component is required to enable it (its not in OPO to reduce cost, just like voLTE support). So can anyone suggest a best charger for me ? Plz dont suggest costly chargers, i just need to most economical one as OPO wont last for more then 2 years from now.
[ONE Accessories] Mr.Ak:
Lmao,the reason why v0lte is not there for OPO is not because of cost reduction.OPO's support was EOL when v0lte came into play.As simple as that.
