So Ebay batteries?

So I know there are a couple of posts on here but I have found them a little hard to follow. I just got my captivate last sunday and on the stock 2.1 rogers rom I noticed that the battery life was very poor. Since then I am now running cog 3.01 i think and my battery life is now alot longer than before.
For the way I would like to use my phone It is still not enough for what would make me happy. my phone is unplugged at 6:00 am and when i get home by 5 it used to be dead but after "breaking in the battery" and the new rom i get home with about %15 percent battery.
I just bought a triple battery pack off of ebay for $10. these batteries are rated at 1500 mAh, the same as the battery that came with my phone. I am just wondering what I can expect from these batteries.
My plan is to drain two of them completely then leave them in my desk drawer(from what I have read if you plan on storing batteries they should be completely drained first) and use one of them plus my oem battery daily(until they start to lose performance). Again does anyone have any experience with a battery of the sort or any similar third party battery?

they are no where as good as samsung oem battery. even though it says 1500mah it is not or will drop drastically after a month or so of use...i've bought a lot of those batteries from ebay and they always like that even some other well known companies like Seidio do not compare with manufacture's batteries. the difference is usable capacity, oem batteries are around 95% compared to cheap chinese ones that are anywhere from 60-80%.

haha thanks that makes sense why they are so cheap, well i will probs by three new ones every months or so.

I have those ebay batteries. I bought the kit that comes with two batteries and an external charger for about $10.
The ebay battery is has about 60-70% of the power of the OEM battery. I have no real hard evidence just from using it for the past 2 months or so.
I am ok that it is does not last as long as OEM because it was only $10 and it came with the external charger. I love the external charger because it allows me to charge a spare battery while I keep one in my phone.

I bought the same ensemble, with essentially the same results excepting perhaps that one of my replacement batteries seems to underperform with about 40% of OEM battery life.
That said, for $10... they're very handy as backups. They'll easily give you a few more hours in a pinch, which is essentially just what I was looking for. I really have no complaints in that respect.
The best strategy for battery life I've found is to buy a handful of wall adapters and position them in places you spend a lot of time at, and to develop a habit of plugging in when you're not moving around.
Sad but true, but mediocre battery life is just kind of a way of life for these (and really all) high-performance Android devices. Excepting getting an outsized and expensive battery replacement like the Seidio 3500 mAh that all but prevents use with many accessories and cases, a couple wall chargers and a car charger are effective if mildly annoying means of managing it.
These generic Hong Kong replacements are entirely effective as emergency supplements, but you'll find yourself preferring the OEM cell still.

Yep I mean for $20 I have two charges and 4 batteries so if I need to go without power , even if not a 100% match for the oem power, it is still damn cheap.

I also got one of these from ebay.
I got the 2x 1500mah batteries + Battery Charger combo.
I must say I am impressed. They are the same quality as my OEM battery. Its so convenient. I never have to run to a charger anymore. Just keep the spare battery in my car or wherever and just pop it in and carry on with my daily business.
When I get home, I just re-charge all the batteries. The Battery Charger even has an LED Light that tells you when its finished. "RED: while charging" and "BLUE: when finished". Charging takes about roughly 3 hours, (just like OEM).
Edit: Been using this for about a month so far. With no problems.. Its the best feeling. My phone is never plugged in anymore. And, I don't have to "pinch the settings" to make my phone last.
IE. lowering brightness to 10%, turning sync off, turning wireless networks off, etc.
HIGHLY RECOMMEND!
only crappy thing is??? I plan to sell this phone soon, when the Galaxy S 2 comes out, if the specs are good enough.

Would you mind posting the link or giving us the name of the exact vendor you ordered from?... I'm about to order the 2xbatteries and charger combo, but just want to make sure I get batteries that are half way decent. When I search on eBay I get about 20 vendors selling similar combos and given that in HK they're celebrating Chinese New Year... most won't fulfill orders until next week.

i wouldnt waste your money unless you just want an extra.

Battery Life Doesn't Matter

(Personal opinion here, of course.)
I don't care about battery life. The battery on the Galaxy Nexus is removable. When my phone is dead, I swap out my battery for another one. Two batteries gets me through ANY day, regardless of usage patterns. Batteries are small and fit in men's and women's pockets easily. They fit in glove boxes, desk drawers, etc. They're portable, lightweight, compact, etc. You can take them almost anywhere.
I purchased the Samsung battery charger kit and haven't looked back. Instead of charging my phone and feeling tethered to my charger all day, I use my phone however I want and swap batteries in/out as I need to, and I only charge my phone overnight while sleeping now. The rest of the time, I only charge my batteries through the charging kit.
All these threads on battery calibration, battery life, etc. just seem unwarranted to me. I'm used to toting a charger around with me, so now I just bring my battery kit (usually it sits in my car, not needed) and if my battery dies, I swap in a fresh one and charge the spare with the kit. This way, I can have my phone on me all the time without worry. If I have no nearby electric outlet I can still take along the extra battery and charge both batteries later. I actually have 3 batteries, if I need them (I can't imagine ever using all 3 in a day).
I don't even use the extended battery. Why fatten up my phone, even if only by a little, if I don't need to do so?
This is food for thought, that's all. Does anyone else just use spare batteries and no longer worry (or even obsess, as I used to do with my Thunderbolt) over squeezing out every drop of battery life? To me, life is easier and better this way.
There's a name for the feeling of not being tethered to your charger all day. I call it freedom. It's awesome.

I see where you are coming from.. What do you think of the battery cover? Is it difficult to work with when swapping batteries and will it last with such frequent use? How do you make sure that your spare battery is always ready (I guess you must be in the habit of always putting it on a charger)?

The battery cover is easy to remove. I ordered two spares when I ordered my battery kit (door covers are only $3 each) in case they wear out over time, which I doubt will happen. Many days I don't even swap batteries, as my phone typically lasts 10-12 hours on the regular battery anyway. I do charge my phone in the car (why not? my phone would just sit there otherwise) which is ~30-45 minutes a day, enough for an extra 20% charge mid-day which helps my battery hit the 10+ hour mark. And if it doesn't, I just swap for a new battery.
The spare is always ready because I always keep it in the charger kit so I can grab it when I'm in need. The kit has a light which turns green when the spare battery is charged to 100%. The light is red otherwise. It's quite handy.
At night I plug in both my phone and the charger kit using the Y cable charger that comes with the kit (allows 2 devices to charge simultaneously on one charger). In the morning, I have my phone and spare, both ready to go.
May I also say, I've impressed a few of my iPhone-using friends with my spare charger kit. They always say "I wish I could do that, but I don't have a removable battery." I lol every time (silently to myself...)

I completely agree. That and who is really not near a charger ever all day? Maybe a few but hey that's what changeable batteries is for.
I see nothing wrong with improving what we have with calibration and optimization though...

Lol sounds like you are super jaded from using a thunderbolt.
IMHO your logic is flawed. Why not get good battery life on one or two batteries rather than mediocre battery life on two batteries.
You shouldn't have to carry around two batts just to get usability out of our device. Two batteries is for when you demand extra from your device.
Like when I went to New York I carried two batteries for my BB9700. Not because it was a battery hog but because I was GPSing and texting all day and didn't want to be stranded with a dead battery. I ended up using both batteries several times skipping charging both of them one night.

edit: I get great battery life on this phone btw. I love it and am very happy with its performance.

I do the same thing. Have the extra battery with wall charger and just throw the spare in my pocket if I go anywhere. Like the OP stated I would much rather swap out the battery (if/when needed) and be able to use my phone like I want than worry about trying to conserve it all day.
I haven't had any problems with the battery cover and even if it did I can buy a new one from VZW for $3.25 with my discount ($4.99 retail) so it is a nonissue.
I honestly don't know why so few people do this. And I very rarely even end up using the spare battery, I just like knowing I have it if needed.

Agreed. I read that stuff to be informed, but no longer out of a crazy desire to extend my battery life because I can't live without doing otherwise. It's a nice change.
Again, I'm not saying anyone else has to or should do this. But it makes so much sense to me, and I like to share what works for me to help others who are looking for other options regarding battery life.

I'm a realistic type of guy. What I want from my phone and what I get from my phone are two different things. To believe they are the same is literally delusional, by definition. To complain about X Y or Z company not providing me with what I want is also a bit irrational if I know that, given today's technology's limitations, what I want might be asking a bit too much. We must work with what we have. I have spare batteries. I use them, liberally if I need to, and I don't mind doing so.
I don't expect a 4G phone to last all day while I play WWF, browse the web, text constantly, check and compose emails, take photos, transfer data, and make phone calls. To get 3-4 hours of screen on time on one battery is great (to me).
I think carrying an extra battery is being more responsible on my end for my own admitted usage of the phone, rather than complaining that the battery life "sucks" or hacking my phone to get an extra 20% battery life (although I'm not against this at all - it's just more work overall). Instead of blaming Verizon, Google, and/or Samsung, I'm taking ownership of the fact that I use my phone quite a lot, and I'm fine with carrying an extra battery or two. Instead of blaming others for the battery life of my own phone, I take responsibility for it and I provide my own solution. If anything, I'm speaking of personal responsibility. And in said responsibility I've found freedom from the dreaded phone charger. Again, it's a nice freedom to have.

I agree completely with the OP. A second OEM battery and quality wall dock charger are my second accessory purchase with any of my smart phones. The first being a good case.

Having a 2nd or 3rd (or 4th!) battery and/or a charger around shouldn't be a requirement for using your device throughout the day. Sure if you use your phone hard then you're going to be used to having a charger nearby, but it shouldn't be a req if you're a normal user.
I don't think its unreasonable to expect a normal (12 hours) days use out of a device. FWIW most people are getting that (especially GSM users), and I don't think the battery issues are as widespread as people seem to think. There are "omg batterylife" threads in every new device forum.

For sure, I'm happy with this phones battery life (WAY better than the EVO 3D) but I like having the extra charged battery on hand for when I'm traveling.

I often go a full day without seeing a charger. Sure I could carry one around and hunt for outlets throughout the day, but I don't think that should be a concern. Just want the phone to be reliable.

For what it's worth, I bought an external charger a couple phones back. Just plug in via USB to the phone if it's running low. Really useful when I'm on the train, for example, and I tether wifi for my Xoom. Gets me through the day in a pinch and I don't have to buy a new one with every phone (though I might buy a larger one now given the Galaxy Nexus' bigger battery).
Also, I usually plug the phone in while at my desk and always charge overnight. But I use the hell out of my phone

I have to agree with Martonikaj I'm afraid. Its a phone, just because you CAN swap out the batteries doesn't mean you should HAVE to to get reasonable usage life.

I disagree with the OP for having 2nd, 3rd batteries in order to use it properly based on user usage pattern.
First, define your usage pattern then try to optimize the battery to support that.
My usage pattern requires to have at least 3 and a half our screen time, and charge the phone once every two days, before I went to sleep (or during the night).
And this phone battery can do that without any problem ...
So, I don't need second battery ... and I am ordering the 2000mAH extended battery for GSM model. Having extra 250mAH is nice, it's a bonus for additional 30 minutes screen time! ... while still having the same look and thin device profile

Hey guys can someone recommend a good place to buy a second battery and charger if needed? Is it worth getting the extended battery and do I need to buy a different back cover if I purchase one? I am in Australia so was thinking eBay might be my best bet? Cheers

I do the same as the OP. I have three batteries that I rotate through. The OEM Samsung battery that came with the phone and two 1900mah batteries that I bought from eBay (which aren't too bad by the way) . I don't ever have to plug in my phone anymore because most of the time I have two fully charged batteries ready to go. I get on average between 12-15 hours on a single charge as it is with pretty good use, so I'm not worried about my phone dying, its just more convenient.

What about if there is going to be an official larger battery for it?

Just bought two off of eBay for $11, bargain. Hopefully they will do the job. Can keep one in the car and one at work, I should never run out of battery

Best extended battery with NFC and compatible case for Galaxy Nexus GSM?

I'm thinking of turning my GSM Nexus into a "mobile computer" - I'm running ParanoidAndroid in tablet mode and already have an OTG cable that I've confirmed works with my 32GB USB drive, and I also have a wireless hotspot with a 32GB microSD card (I connect to it via Wifi and it kinda acts as cloud storage); I intend on adding a bluetooth mouse and keyboard at some point, but that still leaves the extended battery and a case for it.
I was originally thinking of the OEM extended battery and an Otterbox case, but from what I understand, the OEM extended battery isn't much bigger and wouldn't offer much longer battery life. In terms of extended batteries with NFC, which have cases to go along with the big battery backs that come with the batteries? I'd love one that features a kickstand too.
And in terms of extended batteries in general (talking about quality brands like Mugen and Seidio, not cheap brands), does the increase size/mAh actually correlate well to the extra run-time, or should I only expect a ~150% increase in battery life for a ~200% increase in size (or something of the sort)?

After battling with poor battery like on my last 6 android phones and trying tons of different batteries. I finally found a system that works for me. I bought 2 spare batteries and a battery charger for my Gnex (LTE) and it's been the best setup yet. I keep the slim profile of my phone and have enough battery power to get through the day with one battery in the phone and one spare with me.
Everyone will ***** about having to pull the back off and swap but it takes 2mins max from shut down to booted back up. And I would rather have my phone be slim then a monster with a huge extended battery.
The other thing I did was I got one of those AA battery chargers for my phone and I will keep one in my car and one in my bag with 2 of my eneloop batteries in it just in case I have an emergency of some kind and need a little extra juice. I very rarely have to use those for myself, but they have come in handy for others quite frequently.

I appreciate the thought, but I honestly don't care about adding thickness to the phone (its a bit too thin if you ask me - I don't care for this thin phone trend at all), and carrying a replacement battery is a PITA because I don't always carry a bag or are in a car (and I don't really have the pocket space for it) and I'd have to take off whatever case I have on the phone (which would be a pretty lengthy process if I'm using an Otterbox or other such case).

Check this. He reviewed the 3900mAh battery for Nexus (Verizon/Sprint) from Mugen.
The international has 4000mAh and it's here

Magus, did you ever find your solution?
I'd be interested to hear what worked for you.

Chinese battery cases

Anybody try any of the ~$15 battery cases on eBay from China? About 10 listings pop-up without trying, but all seem to be the same, from the description anyway... Just seems like for the money if it even extends battery life 50% it is a bargain.

Very interested in hearing back about this. Bought a new phone for Dad so I am going to reuse his old nexus 5 as a second phone. Will try to pimp it out and the first thing I need is exactly this. Been researching on "larger batteries" (all fake lol) but I believe this is the next best thing.

Any news on this? Seem very interesting. Will also buy a new battery, but this will be better than the LG G2 battery mod.

Sorry... Forgot about this thread. The battery case worked fine although I didn't get to test it much as I sold the phone and case a couple weeks later to a guy in rough spot for next to nothing. He is still using it a few months later with no problems.

I got one of this and I rather use power bank to charge it
Cons:
Little to no protection on the phone, I have to cut a rubber case in order to use it
No pass-through charging. The case itself will NOT charge when your phone is in the case. At the end, you got 100% on your phone but 0% in the case, even you have already plugged in. So if you need to charge both devices, you have to take them apart and charge them seperately.
Slow charge rate, the case charges N5 slow when you are using it at the same time, so the juice perecentage will probably still drop, but slower.
Heat. This thing is warm or even hot when operating under heavy usage. With its build quality, I did worry about something bad could happen.
Comment:
It is not so good and the build quality is also average. But since it is the only battery case that we can buy after 3 years, it is still useful as a backup battery. Just don't use the phone heavily on the go when the case is chaging your phone. (That's why I switched back to power bank…)

Is this Battery Case Worth Buying?

Hi guys.. I'm thinking about buying this battery case for the mate 20X. It says it has a battery capacity of 6000 mah. Does this mean that this capacity is separate from the 5000 mah the phone has, so that I get a combined 11000 mah?
Has anyone here bought it? Is it worth buying?

Just some helpful advice from a recovered extended battery case addict. In the early days when phones didn't have quick charge and we're about 25-50% smaller, I always bought my phones based on the support of manufacturers making extended battery cases for it. As the phone market matured, batteries became bigger and locked in, I noticed that my power consumption was less likely to hit the max of the stock battery. The weights of the phones increased as well and I noticed a chronic pain on my pinky. This combined with the fact that the extended battery cases didn't have quick charge, rapid charge, super charge, it whatever "special" charge came with the phone, as well as a key missing feature of charge passthrough, caused me to drop the extended battery madness. I expect you to come to this conclusion on your own, because like me, you won't be convinced of extended battery cases being a bad joke until you see it for yourself. Make sure there is a good return policy.

Hi techronico,
Appreciate the reply. As far as quick charge goes that will damage the battery in the case the same way it can damage the battery in the phone. This is why I have a slow charger to charge my phone healthily instead of risking permanently frying the phone's battery which will shorten its life. I'm no fan of quick charge.
Regarding pass-through the seller confirms that the power case is equipped with heat, overpower and temp protections. What do you think?
Just to be sure the power case doesnt degrade the phone battery do you think its best to charge the phone case and phone separately and not connected together?
Looking forward to your reply.

I would never spend money on anything like that since I can get 2 days on a single charge on my 20X. All the new phones now use LiPo batteries (the same cell type used in Tesla cars) and have no problems with quick charging and don't exhibit memory as it's predecessor battery types used to have.

Hi ben,
I'm not talking about quick charging. I love slow charging.
Anyway I get 3 days from my 20X. The problem is when I have 30% left it starts to drain like crazy. Thats the reason for wanting the battery case.

Did you get the battery case in the end? They are available very cheaply now from Aliexpress. I don't really have a problem with battery life but am thinking it might be a nice gadget to have
