My own opinion :
1 - pros :-
--Considerable increase in life time compared to increased size of the phone
and I see it in this way the best solution ,
First, size of phone isn't increased badly , and the shape and the style of the phone still great , perfect to hold and still have the looks ,
Also you don't have to get rid of your original battery as other solutions like ( buying 2400 mAh Battery which you'll have to through away the original battery , and stick to only new plus you have to change the back cover with ugly one except for the original 2000 mAh battery which also will not give you the same increase in battery life )
--adding 1300 mAh to 1650 mAh that is to say 2950 mAh is a grat deal but I don't think it 's calculated this way,
as it increases battery life from 40 to 45 % according to my experience . so lasts over the day with my kind of usage , I think it adds hour and half of ( screen on with highest brightness ) time , i.e heavy usage of hour and half to two ( according to my trials ) .
--it works as cover for your phone so really protects the camera ( I 've got a lot of scratches on the Camera, so I wanted something to cover it )
2 - cons :-
-- no support to Usb OTG , who know the configuration of the cable will know why it doesn't support that , as if it does , it will show a notification label " usb OTG connected all the time "
--no power button to shut it off when don't want to use it , although I see this is a useless feature , why I bought it in the first place to turn it off !
--long charging time , adding 4 hours to the original 4 to the battery that is 8 hours charging time , so be sure before you go to sleep to plug it in , or you will have to charge every piece apart ( to get only 4 hours ) . so as to save some time , although I see it normal , as it is not a single battery , it is two separate ones
so expect to spend long time charging it , but in terms of "worth it" , yeah , it gives you your charging time back
--no power cord included , you have to charge it with the one came with the phone .
3 -Additional '' to know stuff "
--tried it a couple of times , when phone is not fully charged i.e. 20% or more , and put the fully charged power pack it charge it up to 40 % or more . , so don't expect it to last much when phone is not charged , it 'll last the time the phone take it to get charged a hour or more by a little , not more .
--when phone is fully chagred thats when it lasts the most , because you only use it now (no power wasted on charging the original battery ) , so it lasts for me 4 - 8 hours according to my usage , and it is great feeling when you look to the phone after 4 hours of usage and still battery full
-- basic thing to get is , some theme or mod to remove the battery full notification , and may be the charging Icon too , I use JKay Deluxe framework for that . because if you going to fully charge it , the annoying battery full notification appears as if you pluggin' it to power cord .

Just another small detail:
MHL adapter is not working with Power Pack. In order to use the MHL adapter (Tv Out function), the Power Pack must be removed.

thanks for this add ,
I didn't have the cable to try it out .

It 's proportional according to usage
...I don't know what you mean by longer period of time but I used it alot ...
It add 40% (40- 45%) to the original battery as average ( act as a charger )
That's to say .. If you have your phone charged to 60 % then put the pack . The phone will be fully charged and the pack will be empty in hour or so the time needed for charge , but it allready gave its juice to the original battery.
According to usage as I said . If your battery usage lasts 10 hours . It will ad 4 to 5 extra ..
For me the power pack lasts ( hour and( 30 or 40 minutes ) )of continous usage ( Screen on , playing games surfing web and wifi on ) compared to 3 hours from the original battery when fully charged .
i.e. Now phone could last screen on up to 4.30 - 5 hours ..

OK,
Thank you on your answer, but can you decide (on/off) when will power pack start to charge the battery or it will been charged automaticaly when the level of juce goes down...?
One more question, does power pack fits the original new 2000 mah battery from samsung because the S2 is a les thinner with that one on it?
Better off getting 2000mah, see for yourself.
Heavy usage.
That's almost 4 hours and 30 minutes of screen on time, unplugged since 10 hours...and still have whopping 50%
It lasts me easy 2 days or more under mild usage and a total of 7 hours screen on time.
I can get through a day very easy and still have a lot of life left for the next day.
I recommend to everyone. Casing may be a problem as 2000mah adds a slight thickness, but I can assure you, case mate pop fits perfectly
Hope this helps someone, anyone and everyone

yes it starts automatically to chage , you can't decide that ..
I don't think it gonna fit perfectly except for the i9100 model by its original 1650 mAh , and as in pictures the power pack have the same curves for the back of the phone , and the 2000 mAh is little bit thicker I don't think it is going to fit it

What !!! that is way better !
7 hours !! how is that !! and 4 hours 30 ! thats great and still have 50 % ! oooh
was your 1650 mAh lasting 3 hours screen on time or my battery have some kindda problem !?
as if 1650 mAh lasts 3 hours so 2000 mAh shouldn't last 7 hours ! it is not that much bigger difference in power ! only 350 mAh increase in capacity gives over 120 % increase in power !!!!!
calculations don't say that ! galaxy note which have 2500 mah don't think will make it either to 7 hours !
the way I see it ( I don't know if it is right )
1650 mAh is less
2000 mAh is bigger
2500 mAh is much bigger
1650+1300 = 2950 mAh much bigger ! should last the most
what Rom you are using ? is it stock rooted gingerbread ?
I'm using ICS LP7 with Syiah kernal 3.2.1 and some other little modifications , I think I'am going to flash a stock gingerbread again to see how it lasts ! but I don't think it will be much !
about the thickness yeah the 2000 mAh I think is the best out there ! it's cover is better than the original in way of holding I guess and protects the camera too . and I don't see it considered as an increase ! it is just making the phone one cool brick .

Here you go guys, usually my battery life would go through to the next day, so that's charging every 2 nights. However, just for you guys..... I've been doing everything I possibly could to drain the battery alas....finally I can get to sleep lol, to show you what an official samsung 2000mah is capable of over 1650mah + power case. I expected less but am impressed with the output it provided even after forcefully trying to drain it. Have a look

Hey
You should check out my final result on my previous post... after a long wait of forcefully draining the battery just to show you guys.... still provided impressive results
My 1650mah would roughly be around 3 more or less hours depending at 50%, by 1% 5-6 hours screen on time.
Let me know what you think, I'll tell you my setup

WOooooo 8 hours !! Way too impressive :thumbup:
I think there is some kindda problem with my phone battery or the Rom or some app is drainning the battery .. Coz it lasts maximum 3 hours screen on from 100 to 1%
If the 1650 mAh lasts 5-6 Hours then adding up to extra three hours is pretty good deal .
I think I'm gonna flash a stock rom with no apps and see how it will last working
So , you 're using custom Rom ?

Yep, I use a custom rom made by a certain group called Hyperdriod. I've been running there roms since 2006 hd2 days. The rom itself is called hyperdroid androidmeda. I use redpill kernal which is also made by them. Regarding modems, I've found LPS to perform great and battery friendly too.
The best thing is, their rom is based off Samsung official stock rom, so everything is guaranteed working.
It has also been specially undervolted using magic config by gecko which also helps with the battery.
That's it really.
Props to all the developers for their hard work. Hyperdroid team are very hard working experienced bunch while maintaining their life. So you know you're gonna expect nothing but the best
here's the link to their rom:

Sorry for answering very late ,
But as I see from your talk
It 's not that much bigger difference , as both , the 2000 mh and the pack are official products from samsung . And from the specs I see the pack has more power ,
For me , I've tried few of custom ROMs , it always have bugs and Issues and need frequently regularly updated , so it 's annoying , compared to officialy stock every year or something it gets updated , plus you're talking about android 2.3.x which is not the last version although it offers better battery life , I prefer stock ICS 4.0.x Based ROMs anyways
Also , you 're talking about undervolting , which for me , very unstable ,and always the phone FC , and restarts a lot , and freezes and slows down ...
I didn't buy a 1.2 dual core to undervolt it to 800 or 1000
And iF it is granted working with no issues , I think samsung would do it in the first place .
So changing in configartion , is not fair in comparison .
From changing between ROMs , yeah , battery life changes dramaticaly , and with some extra apps like Facebook , twitter , skype , whatsapp , or some feeds or RSS ,that's to say with getting benfits of the phone , battery drains a lot quicker .
So it is fair to say the power pack add 40 - 45 % to the battery whatsoever ..
If it lasts 6 hours normaly so it will be 8 - 9 h
So if you want to compare , compare it to the original battery of yours , with same usage , not mine ,
And as you've said 5-6 h normaly to 8 ..it adds as the same or maybe less than the power pack .

As you like , You can charge by both ways .
But if it is charged through case it takes long time up to 6-8 hours
So Before going to sleep , leave it to be charged
Or when wanting to save time , charge the phone and the case separately simultaneously so to take up to 3-4 hours

I bought my yesterday, I am still testing it, hoping for some extra BATTERY juice for my stock ICS 4.0.3.
first test - 43 % phone charged - bit more of half actual power pack capacity 1300mAh
second test - 45 % phone charged - main difference I connected power pack immediately after its charge
I think that's it - no more power
My calculation is 1650 mAh + power pack approx 700mAh equal 2350mAh
Hey guys , i recently aquired an LG G4 H815 powered by android MARSHMELLOW V20g , the battery drains really fast and i didn't figure out why until i realized that the screen uses up to 68 % of battery power , though i reduce brightness to the minimum , nothing really changes , please help
That is normal. The screen using that much battery is a good sign. The more the better.
On max brightness, the screen uses a fixed amount of energy so if you're using 62% on the screen, it must mean other apps aren't misbehaving.
Tap on the screen and check the screen on time. It should be between 3 hours and 5 hours. If so, everything looks good.
Yes i agree , it's definitely logical , but is there anything i can do to reduce battery draining even a little

Even non root try to disable all non used apps disable sync and gps.
Also shut of data or wifi when not used, Use facebook on the web not the app major batt hog
my g4 normally got me only 2 hours of SOT which is horrible.
It's really frustrating man , and i absolutely deactivated unused apps as well as mobile data , sync and gps , actually everything's off , i made sure of it when i did a hard reset , it's abnormal as a friend of mine has a similar phone , but he hasn't the stupid problem , is there any version i can trust to flash , i have a 6.0 v20g
c'mon guys i'm really out of options
update guys , it's about the phone's battery , when i stopped using the usual charger which was really fast , about 1000 ma according to ampere app , and switched to another slower one , after a few days the battery somehow went to normal , can anybody explain why , was the battery just getting used to the slower charger ?
You should buy a spare battery with it's charger. The G4 battery is not that good even with optimal configuration.
Enviado desde mi LG-H990 mediante Tapatalk
Yeah, well... it's always better to use the manufacturer accessories, in this case the charger. Yeah, we know that Marshmallow uses more battery than Lollipop but the difference is not that obvious if you use the right charger. I've tested and Marshmallow cuts my SOT with roughly 40-50 mins...
That's the real problem , it's when you don't have the original charger , or let's just say you have no idea if the seller would give it to you as the phone was being used , you definitely have to figure out how to pick the appropriate one , any ideas ?
c'mon guys there must be a way to distinguish between a fake and an original charger , for example through monitoring amperage or may be voltage , i just need some clue , anything !
Hi.
So purchased note 10 plus exynos a month ago.
Just wanted to find out other user experiances to help me to decide if I need to send phone away or my expectations ware too high.
So 1st would be camera specificly anything recorded at 60fps 4k and 1080p.
Indoors with good lighning anything at 60fps recording looks blurry and unfocused compared to 30fps.
Disabled scene optimizer and stabilization still same blurry results at 60fps
If its possible to someone record a 4k60fps video indoor for me to help to compare.
And the 2nd would be battery life.
Not charging over the night .But usualy charge it once I wake up.Waking up at 6.30 and taking phone of charger and leaving home at 8am.Around 16.00 I am left with 30% battery with 4h OST used no gaming just music streaming ,browsing internet and youtube.
Most apps are set to sleep ,battery to optimized ,screen brightness at 40% ,no Bluetooth,NFC ,4g just wifi /NO auto sync /no AOD .
As well using naptime to doze up system when on idle.
My old S8 plus with custom rom had better battery life and with 4k60 cam mode even better recoding.
As well did factory reset on the phone.
Might be something wrong I am doing ?
Any help would be appriciated
You got a lemon. Return it and get a replacement.
For the battery part, i'm on a exynos model, i can confirm i have the same ****ty battery idle drain as yours (5SOT max). Aprox 2% per hours on idle with some tweaks to improve it, and i've already did 2 factory reset, and tracked everything that could drain the battery with BBS ! That's horrible... But i'm getting 10% drain with the screen on, which is good (9hrs of SOT theoritically)
Awesome my luck has been against me for these couple months .Sent monitor for repair arrived damaged none took the blame that was 700euro in trash.
Now I spoiled myself with flagship phone witch makes me miss my S8 plus.
Guess will send it to repair service next week and wait 10 long days till I get it back.Bad part that here in ireland all the repair services even those witch are sponsored by Samsung is crap.

You can reduce standby drain to 1% per hour by choosing the medium power saving mode, and you won't notice much difference in the performance ( I even keep always on display on)

Can confirm this. Also snooze all your apps you don't really need the notifications from. It really makes a big difference.

It is true that i have debloated it, and have most apps on deep sleep (except mail and few other), so i limit background activity.
I also use "galaxy max hz" mod so i can force low refresh rate and batery saving on screen off.
Thank you very much. I'm thinking about s20fe and 21fe. However, when I watch yt and see what are the temperatures or the results on the battery, it rejects me a bit
I understand. I moved to s21 FE from upper mid range galaxy a8 (2018). I i would say that battery efficiency on s21 fe is a bit lacking. I am not a power user so with the old phone i needed to charge oproximately every 5 days. With this one optimised as best i could i reach 3 days, maybe 4. I know that it has bigger screen and faster refresh rate and those things impact battery life a lot, but i would say that snap 888 has an inefficient standby or the low power cores are still too power hungry for my taste...
Don't get me wrong i love the phone, and am happy that i switched. The main reason for me was getting an upper range camera sistem at a low as possible price, and i bought the phone through a samsung trade in program. Also in europe it is realy hard to get any galaxy phone with a snapdragon procesor...
Hope this helps you in deciding.
