1800 mah battery with stock cover!

I just thought I would share this just in case if anyone was interested. I bought this battery for my Samsung Captivate and it works well. So I decided to out try it in my Focus to see if it would fit..it fit perfectly!! I have had the battery for only 2 weeks now but it does work better and it looks to be Samsung OEM.
So just to recap this fits with the stock back. It is but you will never notice once it closes

Just to clarify...this 1800mah battery fits under the OEM samsung focus cover?? Can you update this thread with usage times?

I would also like to know if this battery is available in EU?

There is an ebay seller shipping to EU.
I've opted for the Chinese 1800 mAh copies as they're cheap, will update with details when they arrive.

Correct this battery fits under the stock cover. This phone isn't my daily phone so I can't tell you how much longer it lasts. What I can tell you though is that in my Captivate (daily phone) it lasts longer for sure, probably about 20 to 30% more. I literally used it in the Focus for like half a day and it had no issues.

Okay I am using the battery in the focus today. It does snap. Lose but it is a tight fight. If you have a case it won't be a problem at all. One corner from my phone unsnaps randomly but one of my clips is broken so that could be the case also.

I received today the Chinese batteries.
They fit perfectly in the Focus and looks like they're exactly the same size. I've started the phone with one and it works fine.
Battery cover is absolutely the same with this one as with the original. I didn't notice any difference in weight either.

I will charge one fully and test it asap and will post back the results.

Could you PM me where did you buy that chinesse battery?

I tested the Chinese batteries and they're weak, as I expected.
They held 3h 05m on WP Bench where as my 1 year old original Focus battery held 3h 50 min in the same battery test, that's 80% of the battery I have now and I remember in NoDo, on WP Bench battery was holding about 6h.
So, they're good as backups, but in no way better than the originals.
The originals should be better, in theory.

I bought the Anker battery from amazon which was around 10 bucks. Its also 1800 mah, but is the same size as the Samsung OEM stock batter that comes with the focus. Seemed to last about 36 hours with light use on my Focus. One thing I noticed - the charging indicator never stops blinking to say that is finished charging. IMHO doesn't seem to give much more than a fresh new stock OEM battery - although for 10 bucks I agree would make a good back up, thats about it.
Here's the link to the battery I purchased:

I never knew about WP Bench. Wish I had. My Focus had 420 or so cycles on it's battery and had a rapid performance decline in charge holding. It also blew up (physically) a bit. I replaced it with a replacement OEM from Batteries +.
The replacement doesn't seem to be the equivalent of Day 1 on the Original battery but maybe Mango and my usage is far more than before.
The knock off batteries, the misrepresented mah ratings, and even the out-right faking of batteries has my jaw dropped. Buyer beware.
I contend that the battery issue, battery fakes, and cheap replacements is 100% the reason Apple doesn't make their battery accessible. They want a tight control over those batteries to guarantee performance.

I just ordered the OEM from first post. When it arrives, I will attempt to do scientific tests and post results. I'll use WP Bench as mentioned before since that is likely the most accurate way to test.
Stock Battery
4:11:57
Airplane mode and NOTHING running…
UPDATE
Ok, Here is a Preliminary set of numbers with 1800 battery...
4:43:19
Same settings and still NOTHING running:
Reason I say preliminary is because this was after the FIRST charge. When the phone finished charging again, I needed to use the phone, so was unable to set it for a test run again. I'll attempt that again tonight. BUT, for the record, I took the phone with me to Reno, NV and used it for over 1 1/2 days without charging. Used the Internet, Maps, and Showing it off to family, taking 15 mins of video during the fireworks, and still had 10% battery left over... I'm really anxious to see what my test results will be this next time...
FYI, it is a fairly tight fit within the cover, but it DOES fit. Once I got all the snaps snapped, it feels very secure.

Could you send us the link for purchase, please?

Yeah, that's strange, the link died on the first post. Here's a link to eBay with a bunch available... Look for part # EB625152VA If you Bing/Google this number, you will find other resellers too.
If you like paying full price, buy direct from Samsung: http://www.samsung.com/us/mobile/cell-phones-accessories/EB625152VABSTD

Larger Battery Tests
Ok, final numbers, photos, and thoughts. The battery is snug, (if you look carefully, you can see a slight deformation on the battery cover where it is forming over the oversized Galaxy battery) but after it is snapped closed, you won't notice as jev3gs has already mentioned. Images attached.
I've made a correction for the time posted in above post (Copied it wrong), and have performed two tests with each battery, so I'm confident that the numbers here are correct. The tests were within about 30 seconds of each other on each battery.
Stock Focus Battery 5.55Wh 1500 mAh
PN# EB575152VA
4hrs 11mins 57sec
= 251.95 Minutes
Galaxy S™ II Battery 6.66Wh 1800 mAh
PN# EB625152VA
4hrs 43mins 40sec
= 283.67 Minutes
This is an improvement of 31.72mins, or 11%! That's using WP Bench which kills the battery very quickly compared to real usage.
That may not seem like much, but for me in my usage, that will likely equate to an extra 1.5 hours per day. 12 hours + 11% = 13.32 hours.
(According to the printed battery specs, you should actually receive about 16% extra, my tests showed a little lower. Maybe will get better with more usage.)
I have not done charging tests yet, but it also seems like it is charging faster. That may be in my head, but it seems like about an hour faster... I MIGHT test that later.
PS: Thank you jev3gs for the heads up on this tip. I was about to buy another battery anyways, so this is icing on the cake!

Thanks for taking the time and doing the review! Let us know about charging times too!

Thanks for the detailed posts SuperSport. I wish the OP had put this before I bought the Momax battery which takes forever to charge compared to the stock one.

Unfortunately, I still have not run verifiable tests to prove the charge times. It does seem faster, but normally, I charge it at night and don't pay attention to when it completes. I've been a bit to busy to run the tests during the day, so it will need to wait for now.
I've bought many OEM and Generic batteries over the years for both phones and Radio Control, and it's really hit and miss. Sometimes, the Generic blow the OEM out of the water, but usually, the OEM batteries outperform.

What do u mean by light use? My stock one, I use the phone for reading news from weave and wp7 news with WiFi enabled, and I got about 5h. I also play games for a little bit. That is my typical day usage.
I wish to use the phone for around half of the day or so, if this 1800 MAh could give me that much of power, then it is awesome

Using my 11% gain as a reference, you could expect 5.55 hours, up from 5 hours. If Samsung is correct, and it's 16% gain, then it would be 5.8 hours. Still not quite 1/2 day...

[Q] X gets hot while charging? normal?

today is the 4th day with my Moto X...and i'm a little worried about my phone because of my battery issues.
the first day i got my phone, it came with 50% of charge and after some usage it got down to 14% but then, suddenly it dropped to 3%. I have some experience with this issue in my previous android phone, so i just tried a charge cycle and it is pretty much ok now.
BUT THEN
yesterday, my wifi was on and i was charging my phone and it went really hot, according to Antutu Benchmark the temperature was 45.1°C (113.18°F)... i quickly unplugged the phone, and it cooled down within 3 mins..
now today morning,
i made the phone shut down itself by draining its battery, kept on charge, i was not ussing it, only wifi was on and the temprature went 44°C (the charge was around 30-40%).. i left the phone as it is.. and then when the phone charged up to 92% it got better (37°C)
IS THIS ALL NORMAL? DO YOU GUYS FACE THIS?
if not, i'll have to replace this, so please help...
apart from this, i noticed that the device runs for a pretty long time at 1% charge

My phone definitely gets warm when charging. I don't have any apps to tell me the exact temperature, but it doesn't scare me. 45 °C is far below what the electronics can handle, and I wouldn't be concerned, it is well inside normal operating range in my opinion.

My battery is currently 102°f on network surfing the net unplugged. I've seen it as high as 113° and have not had any issues with the battery. I'm still getting 24+ hours between charges.

have you guys seen your X go as hot as 54°C??
its a moth with my Moto X, and it gets hot REALLY EASILY, like do a little bit video recording or take some photo spheres or maybe just play candy crush while charging it goes 48°C
and once... i kept a lot of files for upload on drive.. and it was on charge... nothing else...i kept the phone aside...and within 10mins it was hard to hold.. 54°C
i am seriously worried.. but not willing to go for a replacement, since the service in my country is too bad.. any help? :crying:

Batteries naturally degrade over time. That simply speeds up the process slightly (light tasks) or slightly more (gaming). I've done it on all my 7 smartphones (including my first from 2011) and all the stock OEM batteries are working to this day.
I've even gamed heavily (when I enjoyed those things..) on my S2 i9100 and iphone 4s and both those phones get awesome battery life to this day. The S2 was even left on a shelf in the garage over an entire winter lol.
It's just the word damages could misguide people so I wanted to clarify.
But charging temperature can vary between two identical smartphones. My first iphone 5 was rather cool to the touch while charging where as the warranty replacement I got (dust under the lens, they swapped it for a new one) I got tends to be warm and even slightly uncomfortable to hold while using the device moderately and charging at the same time (same charger). It's just variance in manufacturing. No two processors are alike, no two batteries are alike.

thanks for your reply everyone... i guess i'll have to live with it..
maybe i'll just avoid using my phone while charging..

New battery, original or fake?

Hi,
Yesterday i buy new battery for my old lg g2, but i'm not sure is it original.
My New battery is non stepped like this http://tanstartrade.ca/images/LG%20BL-T7.jpg
Do you think that it could be authentic?
Thanks in advance for your help.

I just got replaced battery in service - they told me that they use original LG parts. When I checked it under the cover, it shows manufactured date 6th of January 2016. It is not allowed by antena strips and curved back cover to have thicker battery and thinner would have less capacity. You could probably try but I don't see any benefits in that.
EDIT: After few days of usage I had to get my battery replaced by the old one. May be bad luck with not properly working battery but more probably faik one (runs for 0-10 mins, weird force charging in no OS mode). When they showed me the "new" battery in service it is thinner than the original, does not have the stepped back and thus makes gap between back cover and battery itself - 2mm of medium hard press. So it was like yours - flat design - no additional stepped part. The service was not authorised service but looked legit and had plenty of good reviews. So it's my experience of flat lg battery replacement stated as original.

Be noticed that all of below information are not yet confirmed.
I discovered the difference between original and fake since searching trough forums and own experience. :victory:
Design od LG BL-T7 battery has not changed ever since. Still the only one with the stepped back side. Should look like the battery on right side of these pictures, otherwise it is nor factory replacement (aka fake):
http://i.imgur.com/2Yt8cvDh.jpg
http://i.imgur.com/hkVpceYh.jpg
http://i.imgur.com/XtEH5AQh.jpg
The main difference is in litle bulk under printing "BL-T7", arrows under the NOM icon and next right is noticeable differnce in T in that symbol, fonts differ and last letter of chineese behind the manufactured day,...
There is a believe that non-original batteries are not that bad at all, only they have poor wiring and connection port which often makes them behave unexpectedly.

I replaced my battery recently, they told me that it's not the original one, its a Chinese made but works well. So far, no issue.

Where did you get that one?

Note that if you face any issue regarding charging since these batteries are years old, then feel free to contact the seller and you will get a replacement.

I bought that same battery. It had no glue residue and the year was rubbed off.
It looks genuine but I won't be able to tell until my replacement screen arrives and I can install them both at the same time.

I bought a 3950mah high capacity battery from aliexpress (so clearly not geniune but for the money I decided to give it a shot). it works fine, got my Screen on time from 2-3h to 5h or more. However, when charging, it will charge up to 95-99% and then, while still plugged in, go down to 83% and stay there. Then when I unplug it and start using it, it first goes back up to 90-95% before going back down like normal. Has anyone experienced something like this and/or know a way to fix it? I tried some battery calibration methods but no luck. Also, since the phone rarely reaches 100% (indicated) it doesnt always reset the screen on timer properly... this makes it difficult to keep accurate track of its performance. when it does work 5h seems to be the usual value.

That one sounds weird.
Definitely not normal.
Only solution is to buy another and test it or return the one you haveDefinitely and try another one

I have contacted the seller but so far they are not replying... I tried the Ampere and 3C Battery monitor the check the voltages and currents while charging. At first, I thought the phone showed the wrong percentage as it was not calibrated for the high capacity (so 80% was actually 120% relative to the standard battery capacity) but it showed that the phone was actually discharging once it reached full charge. Also, my assumption of it being 120% was wrong since the percentage probably comes from the cell voltage. So, next I checked the cell voltage using both ampere and 3C but the values were all over the place, jumping from 4.36 to 4.2 and back. this made no sense. The battery has a top voltage of 4.37 when fully charged so maybe the battery monitoring software of the phone is confused by this?
In any case I will wait for the seller to get back to me and if the problem becomes worse I will get a new battery to test out.

Thanks for the update.
Keep us posted on how it goes.

Hello guys, I am looking to buy new battery for my 2 and half years old g2. So here are my options:
1) Pollarcell - they says it's great battery, but still kinda expensive for a non-oem battery. It would cost me about 25e.
2) OEM LG battery - in LG official service, I have to check it they still got them, price was about 30e if I recall correctly.
3) Some random battery - I guess this is lottery.I can get good or I can get bad battery. There are many brands, and their price is from 8-9 to 15e.
OEM is best choice for sure, but I don't feel like investing 1/3 of phone price in battery, especially cause I don't know how long I will keep that phone. Dunno what to do
Edit: Did anyone tried this battery? It has quite high rating
https://m.aliexpress.com/s/item/32572840069.html#autostay

Beware of Pollarcell batteries I have read cases of burning

Bought my new battery at PhonTrading24 ,
Battery is class and from new production 12/2016 .

fake or original?
I also changed my battery after 3 years at LG service however I have some questions in my mind whether battery is fake or original one. Although new battery has same capacity like old one but it doesn not last like new one ( it lasts almost a day ) Pictures are attached new and old one. What do you think guys?

It looks like the original one and it might well be. But that also means it is not new, as the production of original batteries have stopped several years back. So what you have is probably an unused but ageing battery.
Batteries start degrading the moment they are produced, just that it degrades at a slower rate being unused (depending on temperature it's stored etc), compared to it being actively used everyday.

Where to get replacement batteries

Oneplus 3 is an awesome phone no doubt (if you don't damage it). However with the dash charging, there's a high chance we might need replacement batteries for the phone after a year or two.
Does anyone know where we would be able to obtain dash capable batteries for replacement? It would be a great disappointment if we are not able to replace it.
*it is a concern because at least in Singapore, there is 0 support despite purchasing a local set. You will be given an email to make an appointment to bring your set down to a location, but NO ONE will respond to your email. Oneplus Singapore Facebook as well as official reseller do not provide any support either.

Why would Dash Charge wreck the battery? Afterall if anything the phone heats up less than other phones, because the charging is handled by the adapter, not the phone.

You have a point there. However, batteries will eventually degrade, so it would be great to be able to do a replacement when the time comes

Most damage to a battery is done at night when you charge a phone when you've gone to sleep, as the charger will put it to 100% and keep it there throughout the night, which puts more strain on the battery. (just look into Sony Qnovo battery charging tech in their new phones).
The dash charger has been proven to change people's charging habits. For example I wake up at 7.30am to go to work at 9am, as soon as I wake up I put my phone on charge. Thus meaning it stays at 100% for less time, and so degrades slower.

just keep your battery b/w 40-80% and it's all good

Awesome! However, the battery capacity seems to be much lower than 3000mah

Stay away from buying non oem batteries. You don't want your phone to be the next Note 7 lol.

Again you wont need a new battery. It degrade really slow. The problem with fastcharging is heat. Batteries dont like heat. Also charging overnight is bull**** since it stops charging when its 100%. Again it doesnt matter what you do.. If u drain it to 0% its not fully empty so really doesnt matter!

Personally I change battery ever 1.5 to 2 years. Batteries have a lifespan and degrade over time. It degrades faster with heat. It's quite disappointing that no one is sellong replacements though.

Exactly. The controller stops the current flow at full charge. It will not top it up if you keep it plugged in such as in the overnight scenario.

The model number on eBay is BLP607.
You'll need BLP613 for OP3.

Maybe after a longer time there will be more replacements, if there aren't already.
If the OnePlus's battery it good I don't see a need for a replacement personality because I change phone after 2 years, when factory support ends and I'm tired of the phone.

I am pretty sure you can't wait to buy a new one before the battery degrade to an unacceptable level.
Like my OnePlus 1, which still has a quite decent battery time, though it has already become my son's toy.
So, don't worry about this too much.

Majority of the users will replace their phones instead of a degraded battery within 2 years. Unless the battery is defective then yea that would be understandable. If you are one the minority who upgrades every 3+ years then kudos to yall for having the will power to resist the upgrade fever.

is there no one who works at one plus and also uses xda?
that dude can help us in getting batteries from the supplier of one plus.
I am using my xperia ZL since 2013. i changed its battery a while ago. now i feel it is time to change my device. moving on to one plus 3 soon.

I think my OnePlus 3 battery is pretty broaken already. Last me for around 4 houers so i need to recharge it several times a day.
I cant find a original battery, so ill probably have to get a not OEM one

Yes I am. Android 7.1.1 and Oxygen 4.1.3
AccuBattery says my battery is 87% helathy and on 2611 mAh instead of 3000mAh, but feels like much less

Sony Xperia XZ1 compact battery - truth or reality?

Hello, i want to share my experience with this phone after 4 years of using daily.
Battery has still endurance about 2 days and more. 7-8 hours SOT.
Only thing, little bit more hot in summer on direct sunlight.
Comparing to other users of devices like apple, samsung, lg etc. is this experience almost impossible.
My questions: What can be real or truth from professional point of view about Li-Ion battery and its very good endurance after 4 years?
Worth for change if its in pretty good condition but 4 years old?

> What can be real or truth from scientific point of view? (if i am still using this phone)
nothing!

Because some iPhone 12 mini user replied to my comment in one review video about my phone and replied to me deeply about batteries and my stupidity, they can degrade their capacity. But i know from using this phone and Z1 compact, X compact, XZ1, XZ2, XZ2c and many, many, many other phones, what is true from real experience POV. Yes, some brands havent so good technology or so quality batteries and many users had bad experience from using their phone for 100-300 bucks fully new, or iPhone. I dont care about battery if i have XZ1 compact but if i am talking about my phone, no one believes me.

noone believes you because it is not true.
i am not saying you lie, but you are mistaken.
li-ion batteries loose capacity with cycles and age. at 4 years of use, your battery should be around 50% its original capacity, if looked for well.
there is no manufacturer magic here. its like saying your gas car doesnt need gas refills becasue its a better brand of car. its really that silly.
only way battery would be around 90% health today is if you charged it to 50% and stored it in the fridge the whole time, you didnt.
btw you should do that with battery spares.

I know this for very long time, li-ion batteries loosing their capacities or degrade voltage after some year usage, but how li-ion battery directly on this phone can stay that long - around 4 years, still with 2-3+ days using daily and 7-8h SOT ? Before it had really similar endurance. Never disassembled.

because it was large to beguin with. now that its smaller it still lasts.
one thing is: if the battery is very large and you charge it every day (which you should) then the cycling is shallow and wont affect life much. couple that with maybe you live in a cold place, and it can last longer that expected.

I am charging it sometimes through PC, but most of time I am charging it with wall charger from Xiaomi Redmi Note 9 pro - on second day of usage (mostly after some 50-60 hours on standby) and my living has around 20 degrees. Also, my friend has this phone also 3 years not disassembled and he is also curious about battery endurance.

Are you talking about these lines :
level: 33
scale: 100

Because it just means that your phone is fully charged (in my example above, it says that my phone is charged at 33%), not that the capacity is still as new.

Why in android i cannot know battery capacity directly like on iOS without testing in Accubattery for 8 hours+- and have primary phone in indisposition state? Is year 2022 and phone batteries are getting old, but maybe it is typical argument of "iPhone user".

When my phone ran stock android, I used to check it from time to time through the service menu (*#*#7378423#*#*).
That's a pity it can not be done in a vanilla/custom android.

This is an interesting question. Mine lasts one day, and I'm a heavy user but not a gamer. I charged it only to 80% during lifetime, but lately had to start charging to 100%
I started to dig and found info, that our beloved phone has Qnovo Adaptive Charging - so I guess it worked But this technology was not used in many phones - almost none. So I think this is most obvious answer. Which is funny if you read comments from 2018 stating Qnovo is useless BUT (big but here) I have no idea if this technology was adapted as software and/or hardware solution. From comments I read it can limit charging rate, and this is what I observe from time to time in my Lineage OS.
Other factors could contribute here:
- quality of used materials, including cathodes and anodes
- chosen technology for those as well
- charging controller - quality and logic (Qnovo?)
- how easy battery dissipates heat - heat is the battery killer
- even quality of included charger - my subjective opinion is, that newer, more powerful chargers, while charge faster, make the phone also hotter. So I avoid them
Another thing to consider - if Sony paid Qnovo, it means they cared about batery life. So other tricks could have been involved.
Also I guess such type of phone was not bought by cool kids / gamers (it is small and not cool . So usage pattern will be different (apps, tasks) which may also change battery wear over time.
In the end OS will also affect battery life. Sony was not adding ton of features to their official ROMs, which could increase battery drain. Of course it was never a vanilla, but still not something terrible (3.6
Were things start to get interesting... If you try to find battery replacement. It is very hard to find battery replacement on the market with original capacity of 2700. While many years after premiere technology evolved. So it had to be sth special about them, as they squeezed 2700 inside, but nowadays you cannot find equal replacement, not speaking about increased capacity, which would be much more fun.

I still use this phone everyday and I would like to know the battery manufacturer.
Few weeks ago I did a battery degradation test, and after 5 years the battery is at 80%. I can use the phone up to two days (no gaming).
Samsung galaxy s3 and s5 batteries last max a couple of years (the battery was at 50% aprox).

To my knowledge, the only batteries that have even close to 2700 mAh on the market are from phones that saw little to no usage over the years and the battery has been kept at around 50% charge after all these years. Which it, to say the least, rare.
The reason for this is that Sony wants us to go pay for a new phone, so they sell underperforming batteries as official replacements. Of course, the Chinese don't do much better either and 3rd party battery manufacturers won't bother to make such a battery because there will be very little orders of such part. Here is a conversation between me and a battery manufacturer in China, when I was trying to design a battery:

Manufacturer:
I recommend this battery because I want to reduce your cost.
If the nickel sheet needs to be adjusted, redesigned and customized, the customization cost is 3,000 dollars, and the purchase quantity is required to be 10,000 batteries.

I was requesting this adjustment so that I didn't have to redesign the whole BMS, but just solder this new battery's tabs to the BMS we have now, hence losing 0 functionality.
Of course, the manufacturer's message was a clear step-back at the time, giving me reason to think the situation through. The next step was clear, however. The main chip on the BMS responsible for OCP (overcurrent), OVP, OCP (overcharge), etc. and reporting battery percentage and temperature had to be localized and wired just like in the original BMS. The only thing that required change was the pad positioning on the PCB for the cathode and anode.
The chip is a muRata internal chip, with untraceable codes: 401C02M8 and 2BN0R420
I replied to the manufacturer last week, asking for their help in tracking down this chip and the connector on the BMS that connects the BMS to the phone motherboard. Here's how that conversation went:
Manufacturer:
I need a little time to reply to you, because I don't have Sony battery, so I'm not sure which connectors are. If you need to make sure, I'll send you the quotation tomorrow for confirmation, and we can do it if you are sure it's ok.
In addition, after the development of BMS, will you have a large number of purchases later?

Me:
More than 10? For now, definitely not. In the future, it depends on how the product will sell.
Click to expand...

It's been 3 days since "tomorrow", but the "quotation" never came. I would assume the situation with the 10,000 batteries is repeated.
So, yeah. If the manufacturers require such high orders, I think everybody could realize why Sony is doing what they are doing and why 3rd parties provide fairly poor replacements, if any.
So, no better battery on the horizon for our beloved, but at least now we know where we need to look.
Plus, on a positive note, the smallest powerhouse alternative to the Xperia XZ1 Compact is, as we all know, the iPhone SE series. Well, they're not much better. Even with PolarCell's (claimed 2300 mAh, but actually only) 2000 mAh battery, which is higher than the original's 1821 (SE 2nd gen.), doesn't hold up any better than the XZ1 Compact. Absolutely huge drain while in standby, up to 10% after 10 hours of standby in airplane mode. Max SOT I've seen is somewhere around 6 hours (hard to measure on iOS, 'cause why would it be easy?). "Investment" not recommended.

Man, congrats for going as far as talking to manufacturer!

And then what? End up buying 10 000? I am talking for real with the guy, not just speculations.
On another train of thoughts, the guy came back with a reply. after a week. He ordered the original battery to analyse its BMS for me and it should arrive Monday.
