Yes please! That would be much appreciated!

P.S.: I bought a cheap china battery from an Amazon person in the UK and that was horrible. Hence, considering to do the mod, but not confident enough to do this without a tutorial
[ONE Accessories] evronetwork:
I'll have some spare time to kill by weekend, don't expect something great but I'll try to explain it as best as I can

P.S. Hope you are familiar with soldering, no need to be great just a bit carefull :D

I picked up a "CUUSEY" replacement 3000mAh battery from this seller: https://www.aliexpress.com/store/2905002/search?origin=y&SearchText=blp571

The first one wouldn't charge, showed weird voltages and temperatures, basically DOA. Screenshot and message later, seller quickly sent a replacement, has been working fine for a week now. The original OPO battery from 2014/10/13 was at 2260mAh with 4/20/14hr screen on/off/combined use, now with the replacement showing ~2950mAh it claims 7/55/34hr screen on/off/combined use. The difference has been huge, from barely lasting through the day, to forgetting to charge and not even worrying about it. I took various screenshots of AccuBattery, and in the one attached I colored the "new" dots red.

I'd like to run this replacement for another week or two for better stats, but I've also got a ZTE battery that I'm transplanting the original OPO controller into. The bare LiPo pouches weighed 48g/48g/55g for OPO/CUUSEY/ZTE and the ZTE is marked 14.9Wh vs. 11.78Wh for the BLP571's, so it should be a nice capacity boost. Not looking forward to soldering nickel/aluminum LiPo tabs, kinda worried about burning down my house, might use metal epoxy instead.

Got this off ebay

Hey all. I'm aware of the disclaimer at the start of the forum but is there anyway of knowing if it's a fake?

Thanks for your help
[ONE Accessories] Inkazzo:
All of your battries 99% not original OPOs cause your Battries Picture in the Shop got all the same Serial number ;)

Also you may find a platic plate inside and some post before i posted a picture of an original Batterie controller so you can make shure
[ONE Accessories] jusefina:
Does anyone have experience with sending their OnePlus One to a service centre in Europe for a battery replacement? I got a quote from a customer service rep online saying it would be 40 euros or so to have it replaced. It's an OK amount IMO for a genuine OnePlus battery. Just looking for experiences.

Thanks.
[ONE Accessories] Rifat94:
please anyone make a full video on zte battery mod, it will be great :) Thanks
[ONE Accessories] sindahouse:
Thanks Inkazzo. The pictures I posted are actual photos I took of the battery not from the shop.
[ONE Accessories] :
Can anyone sell zte battery mod on amazon or ebay? It is easier to buy it than do the mod.
[ONE Accessories] nicerous:
I would be Interested as well. I still love this phone and see no reason to buy something new for a ridiclious amount of money. What did Oneplus tell you about a battery replacement and to which location do you have to send the phone? 40€ seems to be okay.
[ONE Accessories] jusefina:
Initially the representative refused to tell me, but I discovered in an email exchange with another rep later that the service centres are in Poland and the Czech Republic. I am worried about sending the phone away in case it gets lost and I am personally also worried about privacy. On the other hand they will factory reset the phone apparently, which I don't want either. I don't know will this remove TWRP and LOS from my device or not. This leaves me only with the option of finding a suitable battery online or finding a repair service who have genuine OnePlus batteries. One repair company in Finland (iHelp) claim they use the same batteries as OnePlus. A company in Germany (Refixxo) also claim the same, but they were unable to assure me that it is a genuine battery. How do I know it's not the same crap I can buy off eBay myself?

I wish I could just walk into a service centre and leave with the new battery installed. Or even better just buy a genuine battery online myself. It all feels unnecessarily complicated. One thing is for sure and that replacing the battery on my next phone must not be this difficult.
[ONE Accessories] Mr.Ak:
You can't without trying the battery yourself.Your best bet is to buy from a seller which is ready to give you a refund in case the battery isn't fit to your liking.
[ONE Accessories] Inkazzo:
[MENTION=5961338]jusefina[/MENTION]

I already used the service in Czech from OPO in case of a mic exchange (RMA) and they are fast.

Im from Hamburg and i got 3 tested battries left all got over 3800mAh, but i do not have any more original BMS controller left...
[ONE Accessories] JonasIsAwesome:
Just installed my SIYAA battery I got off AliExpress. Will take it for a spin for a few days and see how it performs. Will try to post results whenever I have something conclusive.

The battery wasn't a flawless fit, gotta say. Got it installed but clearly not up to OEM standards in terms of dimensioning. It ever so slightly smaller than the original battery. I wouldn't have noticed by eye, but the original battery doesn't fit in the SIYAA battery packaging, so right now I don't have my hopes up too high.

In line with previous discussion on here my temperature sensor is (perhaps a bit worryingly) stuck at 25.2°C. Hope it won't pull a Note 7 on me :eek:
[ONE Accessories] Inkazzo:
All of the Fake ones i recived do not got a temperature sensor and all of these batteries where showing 25.2°C all the time ,because there is no real sensor ;)
[ONE Accessories] fradbari:
You're talking about some seller like ebay shop?

In my opinion is difficult to request a refund, because is difficult to show that the battery doesn't guarantee the nominal current....

Have you experienced something similar?

EDIT: it's my impression, or the only way to buy a genuine battery is to buy it from official store (and have near 3100mah)?
[ONE Accessories] elialitem:
Just sharing my experience as well, I used the original OnePlus support and I replaced the battery out of warranty for 40€ here in Europe. Phone was sent to Czechia e came back with a brand new battery. Pick up and drop off with courier. Turnaround of the service, exactly one week. Totally worth it.
[ONE Accessories] Monocog007:
Just got the battery today. Initial thoughts are that it looks like a battery!

I just tossed it in the phone, I'll get around to a review after I've used it for a few days. So far nothing out of the ordinary.
[ONE Accessories] ninjasumit:
Congrats!

Please install this app https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en

and post screenshots after 2-4 charge cycles. It will be a great help to me.
[ONE Accessories] chenrp:
any update yet?
[ONE Accessories] demariafederico95:
I received one two weeks ago.

The battery is 1~2mm shorter

The connector is not exactly in the right position to fit well (2mm on the right)

Battery doesn't keep the charge and barely last one day (the original 2 years old battery last longer)

Quick charge is supported

~2h SOT

I've obtained a refound from the seller, now I'm waiting for another battery from another brand (X-Longer)
[ONE Accessories] ninjasumit:
Those who are saying that its impossible to know anything about the battery from an app, Accu​Battery gives pretty accurate results. I have tested it on 3 different phones and the results were very close to the actual values. For example, It estimated the battery capacity of Moto Maxx as 3891 mah which is very close to the original 3900 mah capacity. I guess none of you tested the app and just judged it blindly.
[ONE Accessories] vable:
may i ask you bought it from which exact store? if i look for example, at the HSABAT OfficialFlagship Store, then really crap load of various batteries are sold and there exist a massive positive feedback. it's hard to believe they make such tossed batteries for oneplus one only. but then again, i haven't seen any store where we can buy original fresh ones and no feedbacks present like "it's a fake one", "don't buy, it's rubbish" etc.
[ONE Accessories] demariafederico95:
I've bough it from A L I E X PRESS.

Using AccuBattery seems to have a capacity of 2700mAh
[ONE Accessories] vable:
There are many stores in there like OP says. I meant which one of these did you used? Please post seller store name. 2700mAh isn't so bad IMHO..
[ONE Accessories] demariafederico95:
Seller was Super Battery Factory
[ONE Accessories] ninjasumit:
You are right about HSABAT OfficialFlagship Store. This seller has positive feedback for all the batteries, whereas the same is not true for other sellers selling the HSA batteries. The other sellers might just be selling a cheap counterfeit of the original HSA.
[ONE Accessories] Monocog007:
Accubattery is reporting a SOT of ~5.5 hours on mine. Also reporting a capacity of 2900mah. Battery will also not charge past 94%. That is from 5 full charge and drain cycles. I can also confirm fitment issues with the power connector. Avoid this seller, they're trying to make me ship it back to china on my dime for a full refund.
[ONE Accessories] captaindyson:
Right, so in light of this larger battery being poor, what would people recommend (ideally with links)? Accubattery has me down to 2650mAh and I feel like it is time to get back up to at least 3000 again.
[ONE Accessories] Mr.Ak:
you have original battery?

Replace it back,never trust any other in lights of original one.
[ONE Accessories] captaindyson:
Sorry, I mean I have the original in at the moment, I am looking to replace it with something good if I can?
[ONE Accessories] Monocog007:
I never ran Accubattery with my original, but I know it was far worse than even the crappy "3600" mah one. At this point I won't bother replacing it again, as I've moved on to a new phone. My Oneplus is just a troubled old soul at this point.
[ONE Accessories] Mr.Ak:
what's the issue with original one?
[ONE Accessories] vable:
battery capacity degradation is the issue. problems on finding acceptable aftermarket battery make me avoid to buy oneplus products in the future. i'm not gonna buy their new products just coz of worn out battery.
[ONE Accessories] captaindyson:
like [MENTION=6337133]vable[/MENTION] said, capacity degradation, if i can return the phone to the capacity quoted on the box as opposed to the reduced capacity that it currently holds then surely that is a good thing?
[ONE Accessories] Mr.Ak:
Yes it's a good thing and original do have a capacity of 3100mah as quoted on the box.So what's the issue and why do you not want to put the original one back?
[ONE Accessories] Traace:
mAh can't be more, as the actual battery size is same as the genuine one. Simple physics :)

I believe they have below 3000mAh real performance, the rest is marketing...
[ONE Accessories] Mr.Ak:
It's easy with eBay Guarantee.Just post a video and some images of the issues with the battery and they'll have you refunded within a week.Atleast this is how it goes on eBay.in
[ONE Accessories] evronetwork:
Sorry for not giving any photos on how to mod the ZTE battery from blade model. Guys it's the best solution I've found check my previous posts on this thread to see the evidence. Now as far as the picture this is when you remove the BMS from the battery(I've use the fake one as I'm not happy destroying the original one as it has some juice and it's my failsafe choice).

The reason I don't have time is due to my job and due to my new gf..spending most of my time in her place, sorry about that ;)

P.S. you don't have to have soldering skills of removing a microusb jack(yes it's hard) ..basic soldering skills required though. Just be careful and don't touch anything more than the nessesary poles(positive/negative)
[ONE Accessories] 3itmn:

Some time ago I thought on do a battery frankenstein for my Oneplus One, but I could't find a good source for an original battery. Maybe this information can help someone.

I found that Samsung Galaxy Note 2 N7100 (EB595675LU) battery should be a perfect match for the Oneplus One, It's also 3100mah battery, smaller than the original battery and it should be easy to find since Samsung sold those batteries. The problem is that all ebay battery seems to be fake ones and amazon in my country doesn't sell this battery from samsung (all are from sellers). And I don't want to do a battery mod with a cheap battery cell.
[ONE Accessories] yogirug:
Just one concern, Is it safe to this battery mod on Oneplus one,because keep hearing about battery explosions.

Also surprised no one seems to raise this question on this thread.
[ONE Accessories] krasny2k5:
It depends on what you do and the cell that you use.

In my opinion if you know what you do, use proper isolation between the battery and the circuit (for example kapton tape not paper tape) and you have basic soldering skills the result should be safer than a cheap Chinese battery cell. And of course using a quality cell from a good manufacturer. At the end, you are only changing the charge circuit from a cell to another, in the RC community is a very common practice.
[ONE Accessories] poronporonpompiero:
Finally the battery arrived :)

Now, before proceeding with the mod, i have some questions...

1) How not to do short circuit? Just not touch both poles simultaneously, or are there other things to watch out for?

2)When packing the battery, do i have to use paper tape or insulating tape? (the battery came packed with the paper one)

Thanks to anyone who gives me a hand!

P.S. anyone got the battery shipped with two chinese universal chargers?
[ONE Accessories] Rifat94:
anyone tried this one? Link: Here
[ONE Accessories] K2pro:
Greetings to all. Tell me, for MOD batteries, you need an original controller or you can use any controller from fake Chinese counterfeits? I really do not want to be left with nothing in case of damage to the controller.
[ONE Accessories] poronporonpompiero:
I think you can use any controller, just be sure it's for opo battery (maybe original ones are better, but counterfeits should work anyway). Using other controllers would cause voltage, current, % problems and so on.
[ONE Accessories] K2pro:
About these same problems people write on aliexpress, when they received batteries for opo. Is everything the matter with a bad controller?
[ONE Accessories] poronporonpompiero:
I read about people that made the mod and got everything working, so the culprit may be bad controller as well as bad installation

Battery for our opo
[ONE Accessories] JonasIsAwesome:
Okay, so I have gathered some thoughts after trying this one out for some time now.

In short: it is not particularly good. To my surprise it actually takes in a full ~3100mAhm, tested using a USB power meter versus my original battery that takes in approximately 2800mAh. Looks good so far, yeah? I got 2½-3½h of SOT in day-to-day use with mixed wi-fi and 3/4G with just over 10% left at the end of the day. The catch however is that the phone drops from about 10% to 0% instantly and turns off. In addition I've experienced a few reboots after swapping the battery.

While raw battery life has perhaps increased ever so slightly over the original battery, it came at the cost at significant reliability downgrades, making the battery 'upgrade' quite unappealing with everything factored in.

About battery :

-https://www.mytrendyphone.eu/shop/oneplus-one-battery-180564p.html

it looks Ok - there is temperature sensor inside

in chat with the people from trendyphone they told that is original but who knows !!!

in use in my phone from two days it show 3000 mah capacity .

has been shipped from UK

-https://octilus.com/accesorios-moviles-oneplus/baterias-oneplus/bateria-original-oneplus-one-3100mah-n131886.html

good quality , but no sensor inside . Capacity after one month of use about 3000 mah with USB counter.

SOT with medium usage 5-6 hours. ( no games or facebook )

I think instead of buying from Ali, let's try one of the two above.

I will keep you up to date .

Please let us know how it goes. If you have a custom recovery and custom ROM, I am particularly interested in knowing if they flash a different recovery and ROM on your device at the service centre. The customer service rep I emailed with told me they will flash OxygenOS on my device, which seems unnecessary to me.
[ONE Accessories] jmax91:
[MENTION=5961338]jusefina[/MENTION] I flashed latest OTA (which have Cyanogen Recovery) via fastboot before send it, so I can't say, but they warned me to backup all my data because it will be deleted.
[ONE Accessories] evronetwork:
Yeap totally safe if you are good with your hands(and a soldering device)

Battery explosions? ...batteries do explode from short circuit ...nothing else. So if you don't punch the battery and doesn't short circuit inside or outside it's safe

Also the short curcuit can happen if the temperature gets way too high(putting the device near a heat element and charging it at the same time)

P.S. In case of regular charging if you sense/feel high temperature near battery REMOVE the charge at once ...something wrong is going on and the battery might explode - You're welcome for the mini lessons on lithium cells :P

P.S.2 2-3 months later battery is kicking hard, no issues at all
[ONE Accessories] poronporonpompiero:
Mod done two days ago!

Everything went fine but i'm a bit disappointed with battery life now. I thought It would be increased but it's almost the same as the old (fake) battery...

Maybe i just have to wait a few days... Or i was just unlucky. ¯\_(ツ)_/¯

I used the battery linked by [MENTION=4447997]evronetwork[/MENTION]
[ONE Accessories] evronetwork:
Give it a time, first charges gave me ~3050mAh but after 2-3 weeks I had ~3.500mAh of capacity

P.S. While on a fake Chinese battery it was the other way around, first charges ~3000 after 2-3 weeks 2.400mAh

P.S.2 and I do treat lithium batteries as best as I can 20-80% charging(never leaving them below 20% and never charging them more than 80% ...to maximize the life of the cell ...this is unless I do a test once in a while
[ONE Accessories] poronporonpompiero:
You're right, it's increasing at every cycle!

Just wondering, having installed the oneplus bms in zte battery will show wrong percentage?

I mean op battery is 100% at a certain voltage, zte battery at the same voltage should be below 100%
[ONE Accessories] virtualspeed:
Wrong. The bigger battery will take more time to reach the 100% but will be at the same voltage as the original one at 100% (around 4.3V)
[ONE Accessories] evronetwork:
No the percentage should be right because it measures the voltage and each battery cell have the same voltage, it would just take a bit longer to reach 100%

Exactly :D ...but as said I don't recommend letting the battery discharge below 20% or charge above 80% if you want to maximize the life of the battery

P.S. If you store a lithium cell you should have it at 60% for maximum life(just some tips on lithium cells) :p

So for the current time being, from where can I order a good battery for my opo? It's been almost 2.5 years now and my SOT has dropped to 3-4 hours for 6-7. :( Help is appreciated. Thank you. Way too many replies to go through so asking directly.
[ONE Accessories] fradbari:
Today i've changed my battery buyed from this seller:

http://www.ebay.it/itm/ONEPLUS-Batt...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649

The first 6 photos are the new battery; the last 3 are the oldest.

Seems similar, excepted the packaging.

I've also done some test, before installing it:

weight of new: 43.7g

weight of old: 50.1g

charged the new one and have (on the first charge-discharge): 9.6Wh against the nominal one 11.4Wh. I'll measure with accubattery for some days and report..

Maybe it's really original :rolleyes::rolleyes:
[ONE Accessories] elialitem:
Now the phone is back at normal use, accubattery shows an healthy battery. At the service center they flashed stock outdated oxygen os and oxygen os recovery, but it took me 2 minutes to go back to my usual Sultan LOS. I do not remember at this time if they relocked the bootloader, but having no memory of it means it was probably a non issue that I got around in minutes. Overall 10/10 would do this instead of buying a suspicious battery from ebay and do the job myself to save 20 euros.
[ONE Accessories] uccollab:
Did the ZTE mod in my oneplus one. Currently testing, will report :)

EDIT: shame on me, I did the first charge while the phone was on, so somehow the OPO got only 3100mAh capacity, and I didn't suffer of the "jump" of percentage after screen off. As a consequence the charging speed was suspiciously high for such a battery (less than two hours). Now, from turned off phone, the battery gains a little less than 30% per hours, definitely more reasonable.
[ONE Accessories] Berth666:
the phone itself don't know the capacity of the used battery - that's not possible.

So it doesn't matter if the phone is on or off when you're charging it.

If the battery reaches 4.3V at charging, its full and shows you 100% - no metter if the batters has got 1000mah or 4000mah.

It just takes longer to load it to 4.3V with a higher capacity
