Mugen Power 1800mAh

With new roms and gps placing demands on battery life, I opted to look for an alternative. Performance hacks can only work so much before your battery dies out when you have an 1100 or 1500Mah battery. I found this battery on ebay from a store and decided to go for it and here's my findings so far....
The model number I'm testing is HLI-P6800SL and will cost you USD48.55
Here's the link in case you wanna check it out:http://www.mugenpowerbatterijen.nl/
Ebay:http://search.ebay.ca/search/search...=m37&satitle=mugen+power+batteries&category0=
*FIRST IMPRESSIONS*
1) Battery is exactly same size as the OEM, had no problems with fitting. Initially thought its increased capacity it would be make it a tighter fit, wasn't the case, PERFECT FIT!!!
2) Turned on my PPC without any hitches or glitches
3) Free shipping, makes this even sweeter...
4) Juicing it up, will fill you in with a much more detailed comparative analysis, my girlfriend is a true test of battery power
5) After some extended use, battery is still cool, haven't experienced any over-heating some users claim
*PRELIMINARY RESULTS*
Having spent a full 36 hrs with the battery...the results are encouraging to say the least. Do keep in mind that for Li-on cells to be fully functional, they need to go thru at least 3-5 full discharge-charge cycles and this is only the 1st cycle.
I followed the manufacturer's specifications about the initial 12 hour charge, also take into consideration that this test was conditioned, i.e. I dished out extra punishment, GPS ON for every trip, BT headset on for every call, backlight at 40% (which is pretty bright) and send/receive set at 5 minute intervals.
I consider myself a heavy-user during the day (less at night) with usage being split data and voice even. I receive approximately 40-60 emails a day (some with large attachments) and make out just about as many phone calls. So without much ado, here are my results...
Testing started 09:30 when I initially placed the battery 100% and ended 02:49 when it finally discharged 0% = 17hr 19m window. So in order to rate correctly and/or approximately I took the calculation values (credit hofo_mofo) of my 1500mah battery
Talk time (4.5 hr)
Current = Rating / Time
Current = 1500 mAh / 4.5 hr
Current = 333 mA
Standby (230hr)
Current = Rating / Time
Current = 1500 mAh / 230 hr
Current = 6.5mA
Run time based on my daily usage 09:30/100% -22:23/ 0% = 13hr 13min window
VERSUS 1800Mah
Talk Time = Rating / Current
Time = 1800 mAh / 333 mA
Time = 5.4hrs
Standby = Rating / Current
Time = 1800mAh / 6.5mA
Time = 277hrs
Theoretical 5.4 - 4.5/ 4.5 = 26% more power
vs.
Actual 17.19 - 13.13/ 13.13 = 31% increased capacity
I will be back to update my findings after 5 charge cycles and will note any increased or decreased performance, but for now very promising. If you use an 1100mah or any other type of battery, do the math and the numbers will pretty much tell you if it's a worthy purchase or not. I am not in any way recommending you purchase this battery, just sharing my findings. So until then....

Also very interested... My Mogul came with a 1500 battery so the 1650 is a waste of time... but 1800 may be worth it.

I have the seidio 3200mAh battery
Have had it for about a month now. The thing really does perform. I use my phone all day long and rarely go below 70% it's great.
Now, if only Seidio would make the rubberized case for the extended battery things would be better.

were do u get the 3200mah battery n how much did it set u back

Seidio. I mentioned the NAME of the battery as in the name of the company. They MAKE the battery and sell it.

Very nice review of this battery. Most of the time people just say, "it lasted a day and a half instead of half a day," as if that is any real indication of how the battery performed. You were very specific on how you use your phone and gave an analysis of your results.
They may not be entirely accurate ( due to the every day changes in your usage between the 1800 battery and original batt. ), but I still want to give you props for a decent review.
Suggestion:
Test the 1800 vs Orig using a stopwatch program and gsplayer like here:
http://www.aximsite.com/boards/vbar...gen-extended-battery-for-the-ipaq-2200-series
That way you will get a more precise comparison.
But again, good review of the battery, you were above par on that one .

how much depth/thickness does that battery add? will it still fit in the stock leather holster?

It added a lot of thickness to the phone exact number I'd check the Seidio site, and no, it won't fit the stock case any more

i bought a mugen extended (fat) battery for the htc tytn ii a few weeks ago and it's performance is a bit strange. while it does add plenty of power to the device, battery drains at normal rate until 14%. then it stays at 14% for a long time before it starts to go down.
so while the battery is useful, the device won't accurately display the remaining battery life. is this the case with this 1800mah mogul bat?

Its actually quite accurate, it doesn't hang like my oem battery. I thought it was somewhat the same after the first time when it hung around 10% for more than an hour or so, then it dropped to 5%. I think when the power is that low, it drops in multiples of 5... just a thought.
Will confirm/disprove when my battery is low, come to think of it I've never seen my original battery at 8% either

That's not Li-Ion that's for the old Nickel_MH or cadium batteries
you should never completely discharge Li-ion battery as that will damage them a bit. In fact there's people arguing you should keep your Li-ion battery as high a charge as often as possible.

Defective battery? Mogul LED blinking Red with Mugen 1800mAh
I ordered the Mugen HLI-6800SL 1800mAh standard-sized battery from www.lionbattery.com last week and got it this past Saturday. I put it in my Mogul and proceeded to charge it as per the directions (i.e. in the phone, not on a cradle, with the OEM AC adaptor). After 12 hours, I tried powering up the phone but nothing happens. Furthermore, once I tried plugging in the AC adapter into the Mogul with the battery installed, I get a blinking red LED light.
I emailed lionbattery.com about a replacement. Is this anything I can fix?
Thanks!

symptoms of a discharged battery or a battery about to discharge (end of life cycle). Best action plan at this point is to return it, here's hoping you kept the original receipt, keep me posted how it goes...
So far haven't had any problems, still outperforming my original battery. Will be back to finish my review of the battery in the next 2-3 days

What I'd like to know is who makes hard cases for these? I have a mogul and no one makes a hard case for the sliding keyboard to be functional as well. What i mean is for an extended battery for the mogul and a hard case like the seidio one (thanks seidio for dropping the ball completely on this one).

I bought that 1800MaH battery today. Also bought this: http://cgi.ebay.com/New-Black-Alumi...15036QQcmdZViewItemQQ_trksidZp1742.m153.l1262
I had a case like that for my Axim, it was awesome. I really dont care that you cant use the touchscreen or keyboard without opening it, I need something rugged and with a high enough ridge buttons dont get pressed. Poor phone rides around in the center console of a Jeep all day long.
I'll post pictures and a little review once I get the items. I also have a good 2400 Mah battery and door I recently got, if anyone wants it I'll ship it in the US for $20. It's 4mm too thick, comes with back door.

Still impressed? The battery is currently out of stock at LionBattery.com

1440 mAh OEM Samsung battery REVIEW

Comparison between the original Nexus S 1500 mAh battery and the 1440 mAh Samsung battery​
General settings:
- brightness set to maximum (100%)
- screen timeout set to maximum (30 mins)
- GPS ON / wireless networks ON (for Google Maps)
- Mobile Data ON
- 3G ON
- Sync ON (Contacts, GMail, Calendar, Reader + SiMi weather each 3 hours)
- WI-FI OFF
- Bluetooth OFF
Services running under the test (I'm not sure these DO have an impact on battery life, but just to be on the safe-side):
- SiMiClock
- 3G Watchdog
- other Android-specific services
Services cached under the test (again, i'm not really sure these count, but I wrote them down in case someone finds something weird or has questions):
- Android Agenda Widget
- Google Reader
- GTasks
- LED Light
- Brightness Level
- other essential Android-specific services
Testing conditions:
- Nexus S i9020-T version, 2.3.4 stock ROM, unlocked bootloader, stock recovery, stock kernel.
- each of the 2 batteries was plugged into the phone, charged till the phone said "Charging complete" (that meant 96% in each case), then discharged till 0%, until the phone shut down by itself.
- keep the screen ON at all times; yes, that means check every 30 mins (because of the screen timeout) and slide a finger across the screen to re-activate the 30 mins timeout timer AGAIN (and again... and again, etc. etc., every 30 mins).
- signal strength 11 asu (+/- 2 asu); check this in Status under About Phone.
- in each test, the phone was placed in the exact same place, it was not moved.
- sync was enabled, but I get emails like one per week, so the sync activity was very low (only Google Reader sync every hour).
- no activity on the phone whatsoever (phone calls in/out, sms in/out).
Battery performance comparison:
1500 mAh battery (top at 96%) = 2h 44mins (the original Nexus S battery)
1440 mAh battery (top at 96%) = 2h 26mins (the OEM Samsung 1440 mAh battery)
In each of the 2 tests, the battery % usage was:
- Display - 78%
- GPS - 14%
- gpsd - 5% (I never saw this thing until now; WTF is it ?!)
- Android System - 3%
Verdict:
Well, the OEM Samsung 1440 mAh battery didn't add up to the performance of the original 1500 mAh Nexus S battery, as I hoped, but it packed quite a punch. The difference between the 2 isn't all that bad in real life situation, but the ~20 mins difference out of a total of 3 hours could scare some people away. Anyway, if you compare it to other <1600 mAh 3rd party batteries out there, I think you will get better results with this one. And, furthermore, it's the cheapest one (I think) at only 5$. How can you ask for more when it's THAT cheap, and made by Samsung ?
In the end, I have to say that for 5$, this OEM Samsung 1440 mAh battery is quite a bang for the buck !
PS: I forgot to tell you where you could ACTUALLY buy one of these if you so desire. Just do a search on eBay for the original Nexus S battery MODEL NUMBER. (AB653850CA)
Additional INFO:
1. The test is a derivate from Ploone's comparison test from his topic over here http://forum.xda-developers.com/showthread.php?t=1058763 Thanks a lot man for the idea and for your video reviews !
2. I hope I was thorough enough. If some of you have questions, please, do ask, because maybe I have forgot something important.
3. Also, if you don't mind and have some spare time for this, could you please conduct the SAME test as I did to see some more results ? Because I still have the impression that my original 1500 mAh battery sucks. Thanks !
*Side-Note:
Ploone's review of the 1600 mAh Mugen Power battery indicated the following results:
3h 25 mins = 205 mins - 1600 mAh Mugen Power battery
4h 32 mins = 272 mins - 1500 mAh Nexus S battery
That's a ~1.327 ratio for the Nexus S battery.
From my comparison (yea, I know there are many variables changed in the testing methodology, but the ratio should stick with the batteries, despite the testing conditions):
2h 26 mins = 146 mins - 1440 mAh OEM Samsung battery
2h 44 mins = 164 mins - 1500 mAh Nexus S battery
That's a ~1.123 ratio for the Nexus S battery.
A greater ratio for the Nexus S battery means that it is more powerful than the opponent. So, because the ratio is smaller in the 1440 mAh Samsung comparison test than the ratio from Ploone's test, that should translate in the fact that the 1440 mAh battery is more powerful than the 1600 mAh battery. It's also 10 times cheaper (50$ vs 5$, aprox.), LOL ! (I'm not judging you, Ploone; I'm only judging that Mugen battery)

Nice review sir, thanks for mentioning me! Appreciated
Sent from my Nexus S using XDA App

As for the charging test, I tested the charge time for both batteries, from 0% until the phone said "Charging complete" (top at 96%); the results didn't vary too much (10mins difference), so I continued the test on the original battery:
1500 mAh battery - Nexus S 700 mA wall charger = 3h 30mins
1500 mAh battery - Nexus S 500 mA USB data cable = 5h 30mins
1500 mAh battery - after-market 1.000 mA wall charger = 3h 30mins
1440 mAh battery - after-market 1.000 mA wall charger = 3h 20mins (-10 mins compared to the 1500mAh) :
60% in 1h 30 mins
70% in 1h 50 mins
80% in 2h 15 mins
96% in 3h 20 mins
Also, I have to add that the 1.000 mA 3rd party wall charger acts like the original 700mA charger. Guess the charging algorithms prevent the Nexus from drawing more than 700 mA (as the original charger can supply). Or something like that. If someone has a better explanation, I'd love to hear it, I'm really curious.

thanks for the review! I wonder if any of the 1650mah batteries found in the new Samsung phones like Droid Charge, Samsung Infusion would fit inside nexus s. Now that would be an upgrade.

Thanks a lot lambda30, I was waiting for this review. I guess I will order one!

You're all welcome !
I think I'm gonna order another one in a month or two, just to have a spare one. At 5 bucks, it's totally worth it. And I'm gonna kill that sucker all day long, instead of being scared that my battery will die on me, like I used to do up until now.
Until now, I just had the brightness at around 20%, Gtalk offline most of the time, Google Reader syncing manual. Now I'm on 75% brightness all the time, everything syncing + Gtalk online all day/night long, no GPS usage, Wi-fi OFF, 3G data on all the time. On the 1440 mAh, it stays up for around 18h with about 2h 30 mins screen on time.
I just finish charging to 96% before going to bed, loose about 10% until morning, and after the day, at about 19:00, I will still have about 10-20% remaining. It's pretty decent.

So are you really getting 18hrs with 75% brightness and 2:30hrs of screentime? I have the original 1500mah battery but I hardly get 10hrs with 40% brightness and 2:30hrs of screen time.(nothing else major). Am I doing something wrong ?

thanks for ur review!!! i m gonna order a couple =DDD

If you don't trust me, do the exact same battery power test from my first post, then compare the results and share them with us. I'm pretty curious.

@ lambda30
Thanks for your research. I know what spare batteries to get now.

I bought two of those 1440 mah batteries from ebay, one for me and one for a friend. I actually received one 1440 mah battery and one 1500 mah battery (says the label). Needless to say, i kept the 1500 mah one and gave him the 1440 mah one (my price for placing the order, haha). I have to say though it performs just as well as the stock battery. While i haven't performed tests or anything, It's impossible to tell the batteries apart performance wise for everyday usage.

For those that don't want to gamble on getting a junk battery or waiting for delivery. Read Amazon reviews for quite a few unhappy customers. Radio Shack has replacement 1440 mAh for $19.99 with 1 year warranty.

Neah, it doesn't happen like that with this one. I've seen the reviews for this item on eBay. Furthermore, with 19.99$ you can get 3 of these and surely, even if 1 out of 3 is broken, you still have the other 2. So again, you just CAN'T go wrong with this purchase.
Furthermore again, I don't trust 3rd party batteries at all. See the 1600 mAh Mugen example from my first post, the one that Ploone reviewed.

Personally I'm going with the cheap OEM. I posted your thread on AndroidCentral and some people sniveled about used/old batteries.
Lithium batteries don't get to full capacity until 4 or 5 charge cycles so that might have had an impact on Ploones review. At PreCentral somline did some extensive tests on batteries and Mugen did pretty well. Here's a link to one that didn't do so well.

Well this (and other reviews/comments) concludes my research. So I'm not just advertising the product/seller.
Personally, I bought it from "accessorymallonline". But, because it comes in a sealed bag, it doesn't really matter from which buyer you get it.

My review of the ZeroLemon LG G4 8500mAh Extended Battery

I have the ZeroLemon 8500mAh Extended Battery for the LG G4, courtesy of ZeroLemon (thanks guys).
Now I've done the (text) review on Amazon and YouTube but you know I like to do a bit of a rewrite for here. In short, this is a case and very extended battery where the case also acts as the back cover. The extension of the battery is basically a rectangular cube stuck on the back of the stock battery. Sounds simple, and it works great.
As you know, my tests for these are basically torture tests. I'm sure some of you who strive for minimal power usage could get over a week of life. However, I prefer to turn off any power saving, throw on WiFi, Bluetooth, GPS etc, use Google Maps on full brightness while I'm driving etc. I have not changed my habits in any way for this test.
For some of the screenshots, I've used Better Battery Stats and Ampere
The initial charge (straight out of box) was reported as 66% and gave about 19hr 30min worth of battery life... straight out of the box without connecting it to a charger.
Test two was to fully recharge (on a QC3 charger) and then discharge: 26hr 17min battery life with 6hr 52min screen on from the last screenshot I took before it powered off, so the actual values will be higher. Again, some high power draw uses, I'm NOT going for maximum possible battery life here.
Test 3 was roughly the same, although somehow Better Battery Stats didn't record screen on time and I've only just realized: 32hr 24min battery life from the last screenshot I took before it powered off, so the actual value will be higher.
One final test I wanted to mention, I recharged the battery in about 2hrs with the phone off. When it was on and I was using it, it took around 4hrs. Very manageable times.
The video version of this review has more details (boy taking all those screenshots took a long time):
Overall, I like it. It makes your phone 18mm thick and weigh 279.9g. I'm just fine with that for the capacity it gives. Remember, those things are preferences, not measures of quality.
The attached pictures are of the battery and case, and then the last screenshots before the phone died on one of the discharge tests.
[I received a sample for an honest review]

Dude omg i waited for someone to write up a review for this battery! Man check out My Thread for my results. Now i have a battery that has 300mah less then yours. Question: are you using a battery charger? (Without the standard charger/cable) and are you charging the phone overnight and does it discharge faster then normal?

Seven hours of sot does not seem like double the standard battery.

Smaller Battery Capacity in Samsung Notes 8 F (European)

Hi all ! I have the Samsung Note 8 F version bought from pre-order. I have noticed that after the last update the battery of the phone is much less and above it gets warmer faster. I was curious about the capacity of the battery after a few months of normal charging without a fast charge from 20% to 100%. I read on the live battery topic about fg_cycle and fg_fullcapnom. Now I have 80 cycles with 3130 mAh capacity. I wanted to check this out and I bought the Stick Charge Meter Keweisi. I downloaded the phone at 1%, I close it, attached the stick and started charging. After 2h the LED turns green and the displayed battery charge is 2921 mAh. My question is why so little? Even I have lost in 5 months of using 300mAh or the batteries have a lower value than the declared one. Thank you!
LE:Sorry for my english!

have 2 F models and can't say I've noticed much difference in either of them, haven't done exact measurements though but both always running high performance mode and easily last a 16 hour day with regular 8 hour on screen time, what I have noticed in al my notes since the Note 2 is that after a while the first 10% seems to drop quicker from 100 to 90 but overall very stable, guessing that it is the phones battery management doing that

I have 4h sot with all on but maybe lost capacity fast this new generation of battery on S8,Note8?
Boss of Samsung mobile say battery lost 5% after 2 years of normal uz.Really?

Try checking with Accubattery app.

I also tried AccuBattery.In the application I had 3250 mAh.The calculation method used by this application is erroneous. If you load up to 80% or less will lower your value and if you drop to 100% in time will jump 3300 mAh. You can not check the battery capacity with the phone turned on because it is logical that there will be more consumers and will enter more mAh when charging. I will do a test with this stick charge meter but with the phone open and sure there will be more mAh to the situation when you have the phone closed. AccuBattery recommends that the phone be charged for a real appreciation to be carried on an airplane.

Hi. I have the European dual SIM version of Note 8 SM-950F and also noticed this. Don't know what to do. Here's my AccuBattery info:

We have tested the battery capacity today with the phone open. I downloaded it up to 1%, I installed AccuBattery and connected it to Stick Meter Keweisi. When I made the green LED I pulled the phone from the charger. I mention that as long as the phone was loaded I did not walk to him. I attach the result.I notice the difference between Stick and AccuBattery.

What build are you on? Just thinking if sammy is messing/patching with charging/discharging limits due to the stupid deep discharge?

I have an European version note8.
Accubattery says 3062 mah.
Fg_cycle is 81 and fg_fullcapnom is 3025.
I've had the phone for 4 months. When I bought it fg_fullcapnom was 3250 mah
Is it defective?

I have exynos Note8 F with vers.N950FXXU3BRA8.

@PlutoDelic,everything that's possible. I can not believe you can lose 300 mAh in 5 months with normal loads.

Question Low estimated battery capacity

I have been using my brand new Tab S8 5G for 8 days or so. I have AccuBattery installed. The estimated battery capacity has been very low from Day 1. Currently I get:
Battery Health 87%
Estimated Capacity 6759mAh
Design Capacity 7760mAh
Based on 31 sessions 1031% charged for 69688mAh
I understand it takes a few days for AccuBattery to function accurately, but I think it's been enough. The design capacity has been automatically measured and already adjusted to a lower value than what Samsung advertise (8000mAh). I've also installed 3C Battery Monitor app, but the estimate is very similar (3718). I have bought 2 other (non-Samsung) android devices in the past few months, but their estimated capacities are much closer than 100%.
Has anyone expericed the same? Or do you think mine is a bad lemon and should be returned? Any insight would be much appreciated! Cheers.

Are you charging to 100% or just 85% (battery save option). If you charge up only to 85% then it is accurate.

Thanks! That's a very good question. I have used the 85% charging limit option for a couple of days but left it off for the majority of time.
But wouldn't it be the same from AccuBattery's point of view if you used the option or not, as the tab tells the app 85% as 85% not as 100%? (or maybe my assumption is wrong).
I have since updated AccuBattery (which cleared all my history!) and started self- recalibrating the app as their website suggests (you go down as low as you can, and start charging until drawing ampere really finishes at over 100%). After a few iterations, hopefully the app will show more accurate info. (Or not, I will just come terms with it!)

İ think accubattery calculates with the Design capacity of the device, with the the Option to charge up to only 85% you would have charged up to 6800mah vs. 8000mah 100%. But i could be wrong too

Just not to open another thread. I have a similar situation with my tab s8+. All apps that do something hardware/battery related report the battery to be 9800mah and not the Samsung claimed
10090.
As for now I'm letting sccubattery do its reading, but so far battery life has been ok for a tablet with high end Specifications. On average I get 8 to 9h of SoT on average not very demanding usage.

Yes my S8 has also a considerable difference between Samsung's advertised battery capacity (8000 mah) vs the capacity apps like AccuBattery read (7760 mah). That's probably their way to prevent users from overcharging their devices.
On top of it, I have also found that my tab can go quite a bit after showing 100% charged. Following AccuBattery's re-calibrating (re-benchmarking) method l mentioned earlier, in one charging episode I saw my tab going up to 8700 mah or so until it started showing 0 or negative charging values about 40 mins after it showed 100%. Having overcharged my tab a few times this way, AccuBattery now shows about 100% for battery health. Obviously this isn't a good way to charge your battery in terms of its longevity, but it might help to calibrate your new device with a battery app. When the % reaches 100%, the estimated capacity on AccuBattery is normally much lower, something like 6700 mah, as I initially got. I need to do more tests, but I find the leeway Samsung spare is a bit too much.
Interestingly, I have also found quite a bit of variability in this 'fake 100% battery' setting across different manufacturers (or at least different devices). I am applying the same recalibration process on my Xiaomi Pad 5 Pro and OnePlus 8T. They are both about 9 months old. My OnePlus behaves somewhat similarly with my Tab S8, showing about 10% extra capacity after 100%, whereas my Xiaomi really stops charging when it reaches 100%.

Hey. This is my stats on my S8+. I recommend trying to completely discharge the battery to 0%, charge to 100% and wait until current is 0 mA. Do this min 3 times in row. Then you will get a more accurate reading
