[Q] Extended Battery Question

I was wondering which extended battery is the best deal for its price? I'm looking for a battery that can get me through an entire day with extreme heavy usage.. thanks

http://gorillagadgets.com/samsung-epic-4g-extended-battery-3500mah-with-back-plate.html
I bought that one and it is doing pretty well. Seriously gets double or triple the amount of battery life of the stock battery. Only thing is it gets kinda hot with custom roms overclocked and the bulkiness gets kinda annoying but thats too be expected i guess. Was kind of weary for 25.99 versus all of the other ones for 50 plus but its really pretty decent.

My experience is that any generic battery for any product performs as good as or better than the OEM at first, but loses the ability to hold a charge after a short time. At that point a double generic isn't much better than a stock original.
I STRONGLY recommend skipping the generic/third party stuff and going straight for a spare OEM. Swapping out is easy, and you won't have the extra bulk.
(This coming from a guy with two 1500mah generics, two 3500mah generics, and two 1500mah Samsungs.)

I currently have 2 generic 1500s and they definitely do not perform as well as I'd like them to. I think I'm going to get the oem like you suggested. Thank you!
E: then again, my stock battery isn't performing that well either..

[Q] extended batteries

Has anyone here tried an extended battery made for the Dell Venue Po?
For example, there's a 2600mAh battery that comes with a replacement cover because the battery is so large. ... It looks nice. I find myself always conscious that I'm churning through battery life just with normal usage.
Related to that, I have noticed my DVP getting pretty warm. Wondered if anyone knows of any tricks to colling the phone, or any gadgets that have been made for that purpose.
Thanks.

Nobody? I'd think that many of the new smart phones would be energy hogs and this would be appealing.

The only replacement batteries I've seen available for the Dell Venue Pro are standard replacement batteries, although an extended capacity batter sounds like a nice idea.
I've also noticed my device heating up during data-intensive tasks, but usually the heat is coming from the panel that is below the battery bay, so it might be something related to the processor/memory strain.

Personally I've been looking for a stock-sized extended battery. The ones on eBay with the extended cover make the phone too thick IMO and ruin the look of it as well.
That said, the kickstand would be handy for Netflix.

Generally I find the stock battery to be far more than sufficient, but when I'm in bad/no reception areas, I find the battery drains super fast.

Didn't like the extended battery

Dvp is quite heavy,, how much more would it get heavier with the extended battery,,, I wonder

Battery replacement
Hey guyz Wake up !!
I cant post the link because I don't post a lot around...
but go to Mugen Power Website and look for Dell venue
(Venue and Venue Pro use the same batteries)
Mugen power is pretty much the only one brand for battery replacement with quality inside.

Venue and Venue Pro have same battery but different backcovers. So XL Mugen batteryes don't usable. Standart size mugen battery is not a pretty much better compared to stock...

You might be able to use the Mugen XL with one of the battery covers from one of the cheap eBay extended batteries.
But personally I'd take the stock sized Mugen battery. I like the stock size of the DVP.

ext bat
I got a new ext battery with cover afew days ago. The dvp is tad bit heavy so
the battery is not a big deal and the new cover is better now you have a finger grip. The dvp does not recognize the new battery at all. I did call seller,waste of time, did call Dell waste of time both have no clue as to how to get phone to recognize new battery. It is a 2600. So I have a few weeks before return to see
if by magic it all works out. Any input? Thanks

Yeah it looks like with the extended batteries, you need to take out and place back the battery after it charges to 1500mah to get it to go past the OEM battery capacity... sounds like the extended battery doesn't have the proper firmware to indicate its full/actual capacity. Bummer... especially since they're not cheap!

Woow, a smartphone.. since it's so smart it doesn't want to have the 'extra' power.. i've been looking for an extended batery for my DVP too, i think it's so much trouble to charge the phone every 4~6 hour or so..

Review Mugen Power 3600mah battery

Hey everyone ! I recently got an extended battery for my Sensation for around $90 as it was much needed to meet my usage !
I thought I would share the feedback with you guys !
Mugen Power is a 3rd party battery manufacturer, and is known for it's "extended" batteries. If you’re an owner of a high end Android phone you too are probably facing a very poor power backup with the stock batteries and that’s where extended batteries come into play.
Basically, Mugen promises something near double battery life with this extended battery life, let's see how this extended battery fairs.
Unboxing
This battery comes in a very small, compact and simple backing - it has a leaflet with the instructions and standard warnings, a back door and the extended battery itself.
Look and Feel
We already know the HTC Sensation is not a very thin device in itself, and by adding the Mugenextended battery and the battery door, it does get noticibly thick - but for double battery life which it promises, the thickness can be bared - at least for me !
One would think that this battery adds a significant ammount of weight to the phone, but on the contrary it does not add any weight which can be significantly felt.
It's also nice to know that the backdoor cover fits perfectly on to the Sensation, and the feel of the replacement cover is not different from the stock one
However, with the extended battery users with small hands will find it a little difficult to hold on the phone for long durations at a go, rest shall be fine.
Performance
The li-ion extended battery which we were provided was rated at 3600mAh which is more than double of the stock battery on the HTC Sensation which is 1560mAh, so was the battery life also double ? Let's find out.
I have been using the HTC Sensation for almost 2 months now and with moderate usage, casual browsing, push email and constant interactions along with a lot of IM and calls, it did last me around 11 hours or so with moderate usage.
But on days when I had heavy usage, with constant data transfers on wi-fi or 3G along with lot of media playback, games, calls and IM - going beynod 8 hours was a tough task for the Sensation.
Now I did spend a nine days on the Sensation with the Mugen Power extended battery, and yes, it works ! And works pretty well following are the figures :
Heavy Usage : 2 days
Moderate Usage : 3 days
Light usage : 5 days
Now let me describe my usage, my heavy I mean constant connectivity either via 3G or wi-fi, 5 email accounts with push email and mails coming in every hour or so on all 5, constant IM i.e. Google talk and Facebook chat, off and on internet browsing, around 40 pictures shot, around 3 hours of voice call, lots of media playback (songs) and even video streaming.
My moderate usage I mean, data connectivity on 2G and wi-fi, push email, selective IM, and 2-3 hours of voice call, with causal browsing and media playback.
Light usage is more like a few texts, some casual browsing and a few calls in a day, with hardly any data usage - more like constant standby.
Conclusion
The Mugen battery is a very good buy and lives up to it's promise of increased power backup. It is a must have for hardcore users and the people who travel a lot, regardless of their usage patterns.
One would however have to bare the slight increase in the thickness of the phone, but amazing amount of backup one gets is well worth it.
But, if you are a light user, and mostly have the phone on standby with a few calls a day, Mugen Power is not for you.
Also note that the HTC Sensation has been known for the "Death grip" issues - but don\t worry the added thickness or the replacement door on the Mugen extended battery does not affect the signal receiving capabilities of the HTC Sensation.
Overall, the battery lives up to the promise of double battery life and has left me much more mobile fearless about the phone battery finishing suddenly !

Is it worth it though? You can buy 2 Chichitec 1800mAh batteries for $40, or other brands like that through ebay

The replacement battery door doesn't look the same as the original battery door from what I can see. Can you post some pics of your phone for us to see

You can watch this video to see how it looks
www.youtube.com/v/s6moi12ZL-4

The back cover is completely different than the original one... It feels cheap and it's not even on the same planet as the original cover.
Also the "8 MEGA PIXELS" mark under the camera is horrible. It's printed very bad and it feels like on fake chinese phones. The battery is awesome, but the cover sucks completely.

Just delivered. Very disappointed, though I have read negative impressions on this forum before... It decreases wifi strength up from 100% to 30%. When you're near wifi router it works fine (like in the video), but when you're 5 metres away from router it drops to 30%.
Does anyone know how to solve this problem? I understand, that their battery cover is extremely bad and doesn't allow to use wifi.. May be there are alternative battery covers for such battery?

Mugen has announced sometime ago on their Facebook that for the Sensation battery they have developed a new backcover that solves the signal issue. Contact them, they will replace it, they always do.

Please tell the date of the message.

Anyway I checked the latest messages in the group and didn't find any mentionings. Only hidden advetisement. If they really replace battery cover to a working one, it's good. But right now I DON'T RECOMMEND to buy it if wifi is important for you.

if you get a powerskin and an anker 1900mah battery, you get the same total size battery power, but also have the ability to remove the silicon case and/or turn off the second battery in the powerskin to be used at a later time, and for half the price of the mugen.

a 1900mah battery is a better alternative than 3600mah? Imho, these are two completely different products that have different purposes. Btw, Mugen offers 1950mah battery as a slim battery alternative.

get a Anker or Evo 3D battery on top of the powerskin and you basically around the same amount of power as the Mugen.
plus you have the option of going slim with a higher capacity battery(anker/evo 3d) then stock 1520 mah and a gel case that comes with the powerskin.
on top of all that, it's about half the price... (powerskins around $40, Anker $10-15)
you tell me which one is a better alternative...

Isnt the 1900mah of the powerskin in addition to the stock battery? If this is the case it makes the two comparable in terms of capacity.

I guess, Anker is really targeting people by selling cheap stuff. I have a phone that costs 700$ and you think that paying another 100$ for a quality battery is a problem? Sorry, I don't believe in 10$ batteries because I have used them in the past and I don't support this idea. 10$ price can only be achieved if a company is cutting budget on smth important.
This is a well known fact: who pays cheap always pays twice.

Product placement
Wow, the OP sounds like a product placement or marketing. It is nothing personal but I read so much comments on Mugen...that it sounds like a rip off.
For my taste your posting sounds a bit too perfect. Like loose 20 kg in just 2 weeks.
I got an Anker 1900 mh and it is perfect. 5 to 6 hours with navigation or 24 hours with moderate to heavy usage...on sense 3.5 - stock kernel. What else do you want....I mean you are not awake for 24 hours...every day...are you?
Just my 5 cents.

I'm sure
My experience. Wanna to be objective:
Positive
Battery works from 14 (high usage) to 25 (low usage) hours. It's very good in comparison with 5-7 hours from original battery.
Cover looks pretty good (in comparison with mugen cover for Desire).
Negative
Wifi and 3G/HDSPA problems
Phone started to turn off sometimes.
If new cover solves this problem I will post the information here. Mugen promised me to replace the cover.
P. S. Your Anker refused to deliver me the battery a long time ago. What's more - they don't have a 3600 mah battery like Mugen.

hey, if paying more makes you feel better, more power to you buddy.
I currently use the Evo 3D battery. I can add the powerskin and I'd have about the same amount of power as the Mugen...
and as a bonus I won't have wifi problems(talk about cutting corners eh?), have a silicon case to boot, AND I would still be paying less then the Mugen setup.
I won't loose any sleep over paying less for quality accessories for my phone.
and regarding the Anker battery... just look at the Anker thread. so many success stories... doesn't matter the low cost, long as it works... properly, which it seem to do.

Good review! Thanks!

By all means, please continue with the pics. I should have my batteries in today hopefully. Never do the expedited shipping with them, it comes just as fast as the regular. I feel stupid for not listening to you guys hahaha

Haha yeah i was pretty surprised with the shipping rates. It was only 69 cents and it took about 4 days to come in. I think youll like it. The reason why people complain about the bulge probably has the s4 on a different carrier. I have verizon and its fine.

I own two of them and was very disappointed I also did a review in the other thread. And if you are following it people are doing scientific analysis of the batteries over stock as welonas physical reviews. And you will see there is little to no gain over stock. Plus you lose NFC and cause an ugly bulge in the back. If you read my review you will see see hat both batteries caused bulge
Hmm what are the chances right! Unless this is a fact! These batteries are lemons and going against the companies mission statement and that's what pisses me off. And these people that are sitting here in denial trying to validate there purchase so they don't feel jipped is comical at best.

Good to hear GnexusPro. Mine also had no bulges with pictures to prove so. I can say from personal experiece I'm getting more battery life, but It cant be considered in reviewing the product as everyone uses their phone differently.

I just got mine. Had to remove the battery label to get it to fit under the standard cover. We'll see what performance is like, not expecting much at this point.

Definitely some interesting reviews . Not quite sure what to think yet besides that its an ok spare battery . The way i use it is i just swap my 2 batteries out so i never really need my phone on the charger . I just finished my first cycle and i noticed that the last 10 percent lasted me a LONGG time. Anyway here are the screenshots from the first cycle. Keep in mind that i was at work today amd didnt charge for a night. I'll pay more screenshots after 5cycles

I'm really beginning to feel that there must be some individuals posting inside these Zerolemon threads that are from the competition side. I say this because I finally got my 3000mah Zerolemon today and I don't have any bulging issues.
I was getting anxious reading all the negative impressions and reviews, feeling fully ready to return the Zerolemon and just buy the OEM battery and charging kit with my 50% coupon.
And to make it worse, my delivery was behind schedule and I only got the battery today (I was supposed to get it on the 5th).
To my pleasant surprise, the battery went in just fine with the sticker intact and the cover snapped on with no bulge. Just to make sure my tactile ability and vision was working correctly, I even had my wifey and mom examine the phone without telling them I had a non-OEM battery inside. Neither of them detected or felt any bulges.
It was, however, more difficult to seat the battery in compared to oem, especially the lower-left corner. I expected super-snugness but it wasnt as tight and bad as I expected. In fact, I had a harder time fitting in the 7500mah battery when I tried to install it for the first time.
I dont know why I'm not experiencing the bulging problems as others. My phone was one of the first batches that went out during the preorder period. Even my 3000mah Zerolemon battery must be one of the first batches because I placed my order for it the day the battery became available and it was shipped out the very next day (although I received my battery so late compared to others).
I do have one theory, though, as to why I may not be affected. Maybe it's because when Zerolemon assembled my particular battery unit, they tightly and flushly wrapped the sticker around the battery, enabling smooth installation.
I'm not saying that all the people who are complaining about the bulging problem are liars and paid-off people. But I have a hunch that we do have some of that type of people mixed in here. And I dont think it's a far fetched idea. After all, the aftermarket battery market is a big and lucrative one and I'm sure there are some desperate and deceitful business people out there trying hard to muck up the competition by spreading FUD to promote themselves.
Anyhow, enough about that and now it's time to see if this battery offers some improvement over the OEM.

Nice results. 400mAH isn't alot, but i think it helps for the people that don't stare at their phone 6-8hrs a day. Times where I'd usually be at 20% im now at 40-50% now.

First full day was a nice surprise. I got 19 hours (2 hours screen-on time) to 20% remaining, whereas I usually get to 14 hours with the same usage. Everyone's usage patterns are different so I wouldn't focus on the absolute # of hours but rather just the lift from the stock battery. Definitely worth the $12 from Amazon.

Best Extended Battery for Note 4? Hyperion, ZeroLemon or something else?

I've been looking around at the extended batteries for the Note 4. Which one do you consider the best?
Right now I'm leaning towards the Hyperion 8000 mah version.
The ZeroLemon does seem to have more capacity, but it does seem to have issues involving the battery reading because of the TriCell design? Can anyone confirm this?
I suppose then that would be combined with the ZeroLemon case. Unless a mod is possible?
By mod, this is what I mean:
http://forum.xda-developers.com/showthread.php?t=2530547
Anyone try something like this with a Note 4 Otterbox?

The reading issues are resolved with a custom kernel such as Emotion, which is patched to recognize the added capacity. I don't have the ZeroLemon or the Hyperion, but I do have this one and I quite like it. It is an off-brand, but I get exactly 3X my normal battery life with it, so it's legit and a good discount alternative to the ZL if you're trying to save a few bucks. I've tried to fit it into my otterbox but it's too bulky. Supposedly the official ZL cases will fit it though.

Zerolemon is pretty good. I don't really have any complains and I get anywhere between 10 to 19 hours of screen time on average with 12-15 being the average. The cover is very beefy and protective. The readings however can be inaccurate and when I sense this I just reboot the phone and it magically adds anywhere between 5-30%. There are some workarounds but they're a bit problematic. It's best to use a custom kernel that is especially tailored for zerolemon or extended batteries in general.
I switched to 5.1.1 on my 910C and flashed http://forum.xda-developers.com/note-4/development/n910c-kernel-5-1-1-stock-tw-permissive-t3206548/ by shreqg2 and it's working well as far as battery accuracy goes. The downside is that it doesn't have the 5.1.1 stock kernel cpu governors and overclocking the stock kernel provides (it can go up to 2100Mhz on BIG and 1900 and 200 Mhz on LITTLE as opposed to 1900Mhz BIG and 1500Mhz (or was it 1300?) on the 5.0.1 kernel. I guess it's not really a big deal since I've been stuck with the lesser frequencies since 4.4.4. Hopefully someone can write a proper kernel with the recently released kernel source code but I'm not sure. Really though, a lot of kernels have extended battery considerations and I'm just testing.
Edit: added screenshots with the new kernel. Rebooting gave me about 5%. It's working very well so far but this is the first discharge since I flashed it. Looks promising. It runs very cool too.

I'm going to be getting the SM-910W8 as I live in Canada (decided to go with it after the disappointment of the Note 5 and because apparently, according to the carrier phone salesman I spoke with, the Note 5 has been having reception issues and they aren't sure if it's hardware or software).
Not sure yet if I will go with an AOSP or TW based ROM though. It's a decision I have yet to make. But so long as the ZeroLemon has the full capacity it should be good. I am tempted though to go with the Hyperion as it does seem to be a single unicell and I have an offer for a cheap Otterbox Defender (which should keep it thin and protected).
Any kernel recommendations for extended batteries and performance in general?

Happy with Anker's 6440mah battery I recently bought, % indicator is accurate and doubles my usage time.
The back cover is slippery compared to the original.

Hi, i take here my "long" experience with extended batteries for different phones. I used Anker and Zerolemon brands.
Since I started to use my Note 4 (last February) Zerolemon's customer care replaced me the battery (10000mAH) because the phone turned off suddenly after only few days of Zerolemon battery use.
The new battery has lasted working fine for about six months but since one month I still have problems even if they are not frequently like first time (now i'm still using the battery..).
I have noticed that when you press at the top of screen the phone turns it off or restarts and I think that is an issue that concerns the contacts of battery to phone. I applied a bit of tape to keep the battery as good as pressed into the slot to avoid contacts issues.
(Probably the battery is too heavy to warrant a good fitting...and maybe the 6400 Anker could be the best solution..)
However I noticed that even when I can ensure that the battery is fine fitted the phone turns off or restarts anyway. In these cases I think that is an internal issue this time.
I don't know if these issues concern only first stock of Zerolemon's battery and now Zerolemon has fixed the issues.
In my experience I remember that I've never had these inconveniences in my S3 phone with Anker extended battery and in my S4 with Zerolemon battery.
I'll follow this thread because I'm searching a best extended battery for my phone...
P.s.: I use Zerolemon case with clip/ holder

Ive had hyperion extended batteries, zero lemon batteries, and others and I have to say Anker makes one of the best batteries for phones, period. Hyperion has some stylish cases for their extended batteries which I love but their batteries aren't one piece and more like 3 pieces attacked and covered with a sticker. I never had any problems with it but its not as good of quality as a zerolemon or an anker battery would be.
Anker extended batteries have a plastic back that holds the battery and is a much more premium battery. Also their customer support is superb. My Anker 7500mah battery went out on my GS3 once and I sent them an email and boom they give me a new case and battery free of charge.
Zerolemon batteries are also known for their quality but they don't try to hide the fact that they make brick sized batteries and that's a downfall in my opinion because a phone with an extended battery still needs to be managable and fairly easy to hold but Zerolemon's 10,000mah BRICK may hold tons of juice but isn't practical. But they still make amazing batteries.

There was a battery thats someone posted that fits our existing case. I am unable to find the link. I think the battery was 5400mha. Anyone what the wed site?

Does the battery other than the original battery does not damage the device ?

How so? Please elaborate

Any extended battery's that aren't all big and bulky?

I bought two of these, so far pretty good results.

How can a stock sized battery have almost double the juice?

Well i know that lithium ion batteries are the 1/4 size of lead acid batteries but we already have li-ion batteries on our phones so im interested to see as how they crammed that much juice in there

I'm a bit skeptical between the Anker extended battery and Hyperion battery, they seem to be about the same size and shape, and the provided back covers look to be the same as well, but yet they have different rated capacities? I only have the Hyperion 8000 mAh so, I can't fairly comment on this but does anyone have both?

never knew Anker made extended note 4 batteries (thought they only made replacement batteries). As its not listed on their website.
Anyways, has anybody heard of Dr. Battery? http://www.drpowerglobal.com/drbattery/model/samsung/sm-n910c/css249r.aspx#rp
says it's a replacement battery, but the capacity says it's 3500 mAh. But on best buy canada, it says it's 3000 mAh.....
Also has anybody notice that MYDE and Anker has very very similar description.
Anker:
We wouldn't give you anything less than the best. Grade A cells chosen from among the top 10%. Rigorous inspection tests to ensure reliability. A built-in IC chip to prevent against short-circuiting. Complete NFC functionality. What does this all mean? In terms of quality, you won't find a better replacement. Don't just take our word for it, though - type in any quick, power-related search on Amazon and see who pops up. As the leader in our industry for the last 3 years running, we know batteries.

hey guys i have been using the zero lemon for some time now, i think its been a year now i believe. it started acting up on me after a year, it would reboot on its own, i know its the battery because i used the standard one and it works fine, (im on it now) so i was looking to see if there are any better batteries, i found one chinese base and said its 5600 mah so when i get it, i will update and let you guys know if its a good buy. they said its standard size and it uses a charge of 4.4 but we'll see. just felt like giving my two cents. how is that ebay battery going since you have been using it? whats the amount of time you are getting on it? my main thing is to have it not run out of battery for just ONE full day. I can care less for a battery that stands 3 days since I do go home and sleep sometime and I can charge it during that time.

It might not be the problem with the battery going bad — I had the same issues: constant reboots after a year usage…
However I noticed it would always reboot while handling the phone — I'd put it down on the table, throw it on the bed. Got me thinking it might be some looseness in the contact — the battery seems tightly stuck in — but anyway I tried and jammed a folded strip of paper in the bottom edge of the battery compartment, so that a piece is jammed under the ZeroLemon battery and a piece on its side.
Since then — zero reboots — the battery is rock solid — so I think after a while the battery gets microscopically loose — it being heavy and all — and that causes the reboots. My paper fix solved that and it's been perfect since!

Very bad there isn't a 25% bigger battery like s5.. A battery 4500 ma with 1-2 millimeters bigger size would be fantastic. I don't understand how so, no Chinese sells one.. Probably they dont want money..

What is your phone model number? can you tell us what is your screen on time (SOT) with this type of battery?
