Battery options: Extended vs. Spare regular battery

Like many thunderbolt owners, I'm slightly annoyed with the battery life.
Is it worth the bulk and cost ($45) to get the extended battery when I can just get a $15 spare battery? The regular battery fits in my wallet. I know a droid X owner who carries a "wallet battery" as a backup.
PS- is there a standalone battery charger for the regular thunderbolt battery?

I went for the extended. Yes, it's bulky but it also makes it through a long day of heavy use without a problem. Plus, that battery door is so hard to remove that I'd rather not mess with it.

The extended battery will certainly do the job, but it adds bulk & weight to a phone that's already no lightweight. And the case selection is pretty limited too. You can get a spare battery + charger for ~$20 on ebay. I can give you a link to a reputable ebay seller if you're interested.

Keep in mind that if you're using a spare battery, it means the phone has to power down, and unless you literally run it to the point of shutdown you aren't going to literally be squeezing every bit of power out of it. You'll get more total time with a 2x capacity battery than a spare.

I would say go with the extended. I only charge mine overnight and it makes it through a full day (5am-11pm). I do turn off 4g when I am at work and when not using my phone however.

A while back I got a 3-pack + charger on ebay for about $20. I haven't had any problems with them. I haven't noticed them lasting less than the original. Either way, I have 3...1 stays in the office, one in my backpack, and one at home.
It does suck taking the case & cover off (the case that I had on my Eris came off faster than a prostitute's panties). I usually have it plugged in for my commute so the battery makes it, and I really only swap batteries on weekends, especially when flashing a buncha ROMs.

I went with these. They are a little more power than stock 1700mah and you get 2 batteries plus wall charger for $34.99. They work very well for me and get me 2-3 hours more time than stock with moderate use...

I tried the extended batter and I did not particularly like the weight and especially the bulk of it. It just isn't for me. I have home, work and car chargers, so I can keep it charged when I need to.

Do the 1700 mAh batteries fit under the stock cover like the 1600's do?

i went with the 2750 mah and love it. battery lasts 14 hrs (no 4g coverage where i live) i got used to the heft rather quickly and love it. now to mod the car dock to fit this thing.

I have a spare standard battery and an external battery charger. Works great. I charge both up every night and keep one in my pocket. Haven't run out of power yet, and I'm pushing the phone pretty hard. (Live wallpaper, oc to 1.5, gps always on, 3g, sync, lots of texting)

I'm really pleased with the extended battery from Verizon. I just left the phone running to see how long it would go and I've gotten 2 full days out of it. It's been running 34 hours now and I'm at 5% power. I'm running bamf 1.7 and I'm in a 4g area. Although most of my time is spent on wifi.
I find that the phone is easier to hold with the extended battery. And the back is hard to remove so it's easier not having to worry about changing the battery.
I picked up 3 - 1500MAh + charger from ebay for $11.34. Link Here
I got the batteries in less than 2 weeks and I had a friend order from the same place and he got his fast as well. I've found these batteries as good if not better than the stock battery.

I bought that same 3 pack on ebay. I keep a spare one in my wallet. Works fine

I've been debating ever since I got my phone two weeks ago if I was going to give in and get the extended battery or pick up a cheap spare regular battery+wall charger and hope somebody will come out with an extended slim battery.
That link posted for the 3 batteries and charger for less than $12 seems like a good deal. I think I'll end up doing that so I can have a battery to carry on me and I can give one to my girlfriend.

I bought both the extended battery and the 1700mah batteries. I only used the 1700mah batteries like a week and got annoyed by the battery changes and bought the extended. Been happy ever since.

I bought from this seller. He is in New York, if I remember correctly. If you are in the continental US, you will get your items within a week.

I ended up going with the Verizon Extended battery and also got the High Gloss case for it too.. Now its complete in my eyes. I got used to the phone being this size now. Not bad at all considering how long the battery lasts now. It rocks.

I would say that you should first install Juice defender free. You will see that your battery life is greatly extended. You don't need root for this, it's an easy install from the market. After that, if your battery life is not acceptable (mine is), then go buy something

Just received my 3500mAh Extended Battery from ebay!

For a total of $13.89 shipped, I'm quite excited about it.
Check out the pics!
I will update on it's performance in a few days.
I'm pretty happy with it so far. Considering the fact that I needed a new battery door (victim of the common "8MP" cracked glass) and wasn't going to pay LG $31 for a replacement.

It's not as fugly as the $100+ 4500mAh Mugen extended battery. I don't think it's possible to design a pretty extended battery.
I don't mind the extra bulkiness for extra power.
I received the battery in the mail at 50% charged. I drained it with heavy use (no screen dimming, stream videos/pandora on 4g) which took 7 hours. I can't wait to use it on a full charge.
I've never been on a phone that lasted so long on 1%. (in fact, it's been on 1% for the past 25 mins with the screen off.
The battery cover fits really well on the phone. I was afraid it wasn't going to fit because I read on a forum that the p900 is slightly larger than the p999.This extended battery was sold advertised for the p900.
This is not true. There is no physical difference between p900 and p999. The cover fits perfectly.

Just search "optimus 2x extended battery" into ebay.

not sure why you are trying to go below 1%, you don't want to completely drain a lithium battery.

Well actually the Mugen 4500mah extended cover is a nice, smooth, consistent shape,and looks dam sexy in person, unlike that hideous weird double box looking cover with four dots at the corners. lol
Also, with the Mugen 4500mah battery, it takes about 45 minutes to an hour with wifi or 4G on surfing the web watching flash videos for it to drop from 100% to 99%. Just 1% loss with heavy usage for about an hour.
Although I'd like to hear more of your observations on this 3500 mah battery. I'd be willing to pick one up at that price just to take advantage of it, if it's not a bogus product.
Anyway these extended batteries are just the remedy our modern generation of cellphones need. Once you use one especially the 4500mah, you'll never want to go back to that tiny stock one...

So it's been awhile since any updates on this battery. It has to be bogus. I don't know how they can manufacture a 3500 mah lithium battery and it's cover for that cheap without it being a scam

I would love to have an extended battery but not at the cost of doubling the thickness of the phone...otherwise I'd have a clamshell Motorola again lol

Think about what you're saying. You rather have a pocket pc that doesn't have the capacity to be away from an electric outlet just so you can look "cool"? It's like wearing a broken Rolex watch just to look suave. That's pretty illogical. Seriously, you might as well go back to dumb phones, because I tell you the truth, the stock battery is not sufficient to make the phone a viable gadget with all it's advanced features.
You need the extra capacity of an extended battery, to be able to fully realize the potential of the G2x and the apps that you can find in the market.
With the 4500mah battery I have from Mugen, I use my phone as a personal trainer, a flash light, a camera and video recorder, a audio diary, a gaming machine, a internet browser and movie player, a tv remote control, a radio, police scanner, etc. without worrying what app I want the phone to be and use it the whole day as anyone of the gadgets a mentioned above without having to constantly think about plugging in and recharging it.
Also it can't be good plugging in the rechargers micro usb often, since it wears and tears. Having constantly plugged and unplugged when I was using stock battery, my charger connection now wiggles and is loose just because I had to constantly charge. Once that breaks good luck on trying to replace it.

Well, my 3500mA batt and cover arrived today.
My original cover broke where it said 8MPx. **** that.
Turns out this battery is awesome - from what I see within 6 hour use.
I got it charged and being trying to discharge it with heaviest load.
Running, browser over WiFi, playing music, benchmarking and etc.
Compared to my OEM 1500mA batt this 3500mA is a BEAST!
The cover also fitted fine, but it looks kinda cheap (but what would you expect for $10 delivered)
I would really recomend it to anybody!
I love it!
PS will post some pics tom, when I get back home.
Look for item # 270770593394 on ebay. $10 delivered!

Well unlike most others here, I don't use my phone so heavily that I'm always worried about it dropping to zero. I make phone calls, text, and browse the web and Facebook here and there. I don't play any games or anything like that. My main battery drain seems to be widgets and texting at this point.
I guess it all depends, but the repeated recharging will loosen the plug gap and that's a very valid point. I will probably get the 3500 or 4500 or whatever it is and try it out either way.

During a normal day, I wouldn't need something this big but for those times I want to hang on the beach all day, this is perfect! I had one for me G1 and that thing lasted all day with extremely heavy use.
Gonna order one.

Want extra battery life? Simple answer is to buy a spare battery!

I spent days, even months trying to make my battery last longer and looking for portable chargers to carry around with me just incase I needed it.
I then realised I should just buy another battery, I have no idea why I had never thought of this before.
So a few months ago I purchased a refurbished genuine battery from eBay for only £4. The only problem now was the trouble of keeping one battery charged while using another. I then found a desktop charger which can charge the battery without the phone (link below)
I use this one
http://www.ebay.co.uk/itm/Battery-Desktop-Charger-Cable-HTC-DESIRE-HD-/290594769249
This one could also be very useful
http://www.ebay.co.uk/itm/HTC-DESIR...DUAL-DOCK-STATION-STAND-DESKTOP-/320793954500
It will automatically stop charging the battery when full, but will still consume alot of electricity if left plugged in.
I've been using this method for about 6 months now with no problems whatsoever.
Now whenever my battery goes dead whilst I'm out, I just simple switch batteries and I have full charge again. It takes 2 minutes to swap batteries, no trouble at all, and a battery isn't too big to carry around, I keep mine in my back pocket or in my wallet.

People want to have ONE piece.
They want to be able to charge the phone when it needs to be charged, but they don't want to look at the percentage every five minutes and fear that the battery will be dead after a day.
Thus they want a battery with more juice.
A lot of people have skins for their phones to protect it and keep the resell value high. Those people might even consider to buy a powerskin which would give them an extra 1500mAh (at a price of course, but that's price vs. convenience).
Others know how to preserve their preciously mAhs.
Normally the phone should drain your battery by 1% to 1.5% every hour. That means it can run in standby and wait for calls and texts for up to 4 days.
Since you normally use the phone at least a bit, you should be able to keep it running on one charge for two days.
The last resort is to keep multiple batteries.
It can happen that you forget the spare. It can happen that you forget to charge the spare. It can happen that it's just not possible to swap batteries because you are standing outside in the dark.
There are just so many points why you would want to try and extend your phones live before you carry around a spare.

I prefer to carry a spare. Takes only a couple of hours to charge, and I always put it in my wallet straight after its charged. It's the cheapest option and imo its the best option. Better than a big bulky cover with a battery inside it that also costs a bomb.

I want one battery too.
I bought mugen power 1500 mAh. It's better, but still not for all day heavy use...
So i order htc Evo 3d with 3600 extended mugen power battery with spare cover.

The external charger thing is awesome. I always have a fresh battery available. Super cheap too. I have 4 batteries, enough to leave one at work, in the car, and at home.

It does seem the easiest and the cheapest option. I tried larger batteries and portable chargers, but none of them would make the battery last as long as I needed it to.
But now having a spare battery with a desktop charger is the best option for me, it cost me less than £10 for the genuine battery and desktop charger, and all I have to do when my battery is dying, is simply replace the battery. Less than 2 minutes later I have full charge. It's not hard, and it's not expensive, I just don't understand why people chose very expensive, and less effective options when this seems the most effective as it's twice as much juice, and it's the cheapest option too, extremely cheap.
The only downside is if you forget to take the spare battery out with you, but I got used to putting it in my wallet or my jeans pocket straight after it has charged. Some people say it's a stupid option because you may forget to take it out with you, but I could argue saying people with portable chargers could forget to take them out with them too. The way I see it is, you get so used to not forgetting to take your phone out with you, everyone checks to make sure they have their phone with them before they go out, and after a week or 2 you finally get used to taking the battery out too. When I first got the spare battery I did sometimes forget to take it out with me, but after a week I got use to checking I had the battery with me, as well as the phone.
My checks are... Wallet, keys, phone, battery, go

Charge
I bought a portable charger for £24 from Amazon, and it's proved really handy for me. It's a 7000mah Tecknet and can charge two devices at once as comes with loads of adapters. Although the spare battery is a good solution it's only a solution for that one device. A portable charger will also charge your back up or 2nd phone, mp3 player, and any other phone you buy in the future. It is as big as the phone so it's easily pocketable. I've considered carrying it in my boxers just to see the look on peoples faces when I unzip my jeans and plug my phone into my crotch. I've also been meaning to test exactly how many charges it does but it's at least 3.

I've got a NewTrent 5000mAh power pack, and it's good for - about - 3 charges. Not easy to be precise about that, since no accumulator maintains and returns 100% of its capacity, but 5000mAh is more than enough.
I use it for mountainbiking when I want to record a track and also communicate my position for 4-7 hours, without having to stop, lose a few minutes and change batteries.
Different solutions will be valid for different needs, but this is easy to charge and easy to use.
And it cost me about €20 off Amazon, which is a lot less than an OEM/Mugen battery.

The only battery that will increase capacity is the Mugen 1500mAh battery. There are a couple of threads already in this forum on this battery.
All the ebay batteries offering the world are, let's say, misleading the consumers.

The Mugen battery are less reliable, also even if its 1500mAh, it may discharge much quicker than our original battery.

How can it have more mAh than the original if it discharges quicker?
Maybe you should think about that for a bit.

Mugen battery has higher capacity!
and for my case, it lasts longer then stock batt.

So I was surfing the intraweb last night and came across http://www.mugen-power-batteries.co...galaxy-s-relay-4g-t699-with-battery-door.html. Very tempting, especially considering that according to Mugen it has NFC. What do y'all think? Should I?

uuh... the relay is already quite thick, with that battery it will be huge... i personally wouldn't, but it's a matter of personal taste

I had an extended battery on my Doubleshot before this - the bulk didn't really bother me. Maybe I'm strange but I didn't mind. Especially with the battery life I got.

i has extended batteries for my G1 one back then. i used them when i took the device with me geocaching. I had two of them and they made the device stay up longer than i ever did
downside with the bulky back covers is, that the device won't fit into any pouches no more. and, of course cases no longer fit either.
but once you're used to the shape - imho - the added thickness is no longer disturbing.

I had purchased a EZO high capacity battery with cover from Amazon--the same day I ordered the phone. That was months ago and I see the battery is no longer available on the site.
That's a shame, because the package was reasonably priced, the cover fits well, and the battery works as promised.
The device can run about ten consecutive hours for me running CM9 without any CPU profiles and with the governour set to interactive.
If I'm going to be away from a charger for a long time, I've found that setting the device to powersave is tolerable for most applications and the battery goes from good to ridiculous...
The additional bulk will turn off some buyers; however, I have found that it makes sliding the keyboard open much easier...
If you can find an EZO battery and you don't mind the extra bulk, I recommend one.

Nope. No NFC.

I've had my Relay 4G about a month and a half now, and am already looking at getting an extended battery. I find myself charging it a few times a day - sometimes I'll only get maybe 3 hours before it's "critically low". Yes, I do use it a ton - it's currently my main computer, since I rarely have access to my parents' laptop and my desktop, whose case+mobo+cpu I recently sent to the recycle bin, bit the dust over a year ago. Also I have unlimited unthrottled 4G on T-Mobile (and used well over 10-12GB last month, & this (billing) month am currently at 12.21GB since April 28.
I've seen the Mugen 4600mAh battery with NFC online around $90 (way too rich for my blood), and the EZOPower 4100mAh (no NFC) for around $17-23 or so at Amazon or NewEgg, among other places. I was originally wary of the cheap price on the EZO, but if the huge price difference is due to NFC and not being a cheaply made battery, I'd want the EZO, possibly 2. I don't use the NFC hardly at all, and I suppose if I really need it sometime I could pop the original stock battery back in for the occasion.
So any reason for me to NOT get the EZOPower 4100mAh? If I get 2, I'll probably also want an external charging solution so I can charge one while using the other. Also is there a hardshell case (with a built-in stand) available that fits the phone with the larger battery door? BTW unavailability of those two things won't be dealbreakers for me getting the battery. I had an extended battery for my G1, and that phone finally bit the dust after ~4+ years. (I wonder if my SGH-T699 will last that long…)

would somebody care to explain to be why nfc is dependand on the battery?
the batteries have just the same 4 connectors as any other cell battery i always had in my hands.
or are they made of materials that don't shield the nfc waves passing though?

nfc antenna is in the battery casing. NFC antennas go for about $5 on ebay, if you figured out which two connectors go to the nfc you could probably set up your own if your battery doesn't support it.

Can anyone confirm whether the Relay accurately reports on the extended batteries? I'm currently using a patched Droid 3, but I'm starting to find its limitations too restrictive, and I'm thinking of plonking down for a Relay.

EZO battery
orange808 said:
I had purchased a EZO high capacity battery with cover from Amazon--the same day I ordered the phone. That was months ago and I see the battery is no longer available on the site.
That's a shame, because the package was reasonably priced, the cover fits well, and the battery works as promised.
The device can run about ten consecutive hours for me running CM9 without any CPU profiles and with the governour set to interactive.
If I'm going to be away from a charger for a long time, I've found that setting the device to powersave is tolerable for most applications and the battery goes from good to ridiculous...
The additional bulk will turn off some buyers; however, I have found that it makes sliding the keyboard open much easier...
If you can find an EZO battery and you don't mind the extra bulk, I recommend one.

I also picked up two EZO batteries. They have a well made cover and last for twice what stock does. Unfortunately it didn't have a NFC antenna and both have now swollen up to the point they no longer fit. While I had left them plugged in after full charge, they seem to stay warm and not tolerate it well. Can't say how well they could have lasted if better cared for, but abuse or overcharging seems to effect them quickly.
Does the mugen or other brands also have issues? If anyone else have suggestions.

Well, it just displays a percentage. It at least seems accurate while logging with Juice Defender's graph, it would track down at fairly consistent rate until charged or out of power. As for swapping over to a Relay, It's about as well supported as any slider out right now. I haven't been disappointed.

the EZObattery rocks. For $19 (I got mine on ebay) I get 2 days and a few hours into the 3rd before needing a charge.
I have the same issue kilr00y mentioned about it not fitting into pouches or cases except I found now that the phone is harder to flip open and safely hold at the same time while doing 90 other things at once which is when I always need to use the phone. I keep an aftermarket case on the front screen part but can't find an extended back case. I made my own from a tube of black silicone but would love to hear it if anyone finds another option. I don't mind if the phone turns into 1988 brick style size so long as the battery lasts and I don't crack the screen again.

I was looking at extended batteries and if I'm not mistaken, there seems to be a genuine extended battery that should work with this phone. Just would need an extended battery cover. Battery model is: EB-L1K6ULZ (Link)

It looks good. Be aware that most "extended" battery will not last long... In particular when they have a lower voltage than the original battery. Lot of battery with higher mAh run at 3.7V instead of 3.8V this make it last shorter than the original.

I've had 2 of the EZOPower 4100mAh batteries, and am experiencing the same problem that stonefoz mentioned about the batteries swelling. In my case, for example, the current one has gotten to where the cover will just spontaneously pop off, and the battery will dislodge, forcing the phone to lose power. Also, regarding his "staying warm" comment - sometimes when I was doing something extensive on the phone, it'd sometimes get so hot, especially the keyboard area, that I could barely hold it, and that concerns me some.
I believe the second one has lasted longer than my first, though. It's not quite as bad now as my first was when I replaced it. I bought my first one May 18, 2013, and my second one September 18, 2013, 4 months later. It's lasted till now, May 7, 2014, 7 and a half months later, but it's about time to replace it.
It looks like it's no longer available, but I was thinking I should try a different one anyway.
One option is this 4600 mAh Mugen battery for about $90, and another is this 5000 mAh MPJ battery for about $35. The MPJ does say it's only 3.7 volts, which according to scaltro could be a concern with longevity per charge.
I definitely would like better battery life. I've noticed that playing FarmVille 2: Country Escape is quite a drain - I'd go from full battery to getting the low battery warning after only something like 2 to 3 hours or so, even with the EZO battery. Earlier, I popped in the factory Samsung battery, topped off its charge, then decided to test battery life playing FV2. I also turned on bluetooth (and sent the sounds to an external speaker), cranked the screen brightness all the way up, and turned off power saver mode, in an attempt to get a "worst-case scenario". I tried turning on WiFi (we have a hotspot here now) but it wouldn't connect to the game server, so I just went through my unlimited+unthrottled 4G.
The results:
2:45am - battery full, unplugged
4:15am - battery 22% (I checked it a few times along the way periodically, but neglected to note the times)
4:23am - battery 14%, had just gotten the battery low popup warning
4:33am - battery 5%, battery critically low popup warning
4:35am - battery 3%, then I went and plugged it in.
So, it lasted only about an hour and 50 minutes from full to 3% remaining. I'm hoping a good battery would be able to go all day and all night and into the next day with similarly-intensive use. (No I wouldn't be playing games the entire time of course!)
Personally, if the $35 MPJ battery would be good enough, and significantly better than the EZO, I'd prefer to go for that one.
I'm wondering, though, if the $90 Mugen is a huge leap up in quality, though (disregarding the NFC for now which I haven't had to use)? It's a bit rich for my blood to drop all at once on a battery for a phone ... BUT, their website tells me they accept returns up to a year later (and I've gone through TWO EZOs in that time), which gives me some hope. If, overall, I'd be spending less by getting one Mugen and it outlasting 4 or 5 EZOs (if they were still available), I'd get that.
On a side note, it'll be a while before I can afford to replace my phone, but when I do, I'd really like a good QWERTY keyboard. I see that very few phones come with them now, though, and the ones that are are near the bottom of the barrel spec-wise. I'm thinking I'll need to get an external compact bluetooth or USB keyboard with my next phone, and expand my options for the phone itself. Ideally I'd like to get one that I can put in a flip case, with the phone in the other side of it, and close it when I'm not using it. (Although, there is the concern with getting the phone out quickly to answer calls, although I maybe only talk 25-50 minutes a month or so.) Any suggestions on what to look for in the case/keyboard department, for example? Chances are it won't be till 2015 at the earliest (and my wallet hopes my Galaxy S Relay 4G will last through 2016 or so unless it dies or something else goes seriously wrong) before I get a new phone, but I like to start my search early. When I do get one, I'm hoping it'll last at least 4-5 years, and maybe stretch it to 7-10 if I'm pressed for cash then.

My high capacity EZO battery eventually bloated and swelled up--after a year. I replaced it with a Mugen battery. Both came with new back covers and make the device about as chunky as a Sidekick II.
My device can run OpenGL applications for about 9 hours straight with the brightness set to 50%. It's about the same for movies. I get decent signal at my house and GPS is disabled when I am not using it. I use Green Power and Greenify to save battery when the device is locked, but that wouldn't affect using the device.
I am on an official Cyanogen nightly, so there's really no battery saving hocus pocus at work here.
Make no mistake, an extended battery will get you about 9 hours of heavy use. I thought I was going to die when I used a stock battery for a week waiting for my new Mugen to replace the old EZO. The device literally couldn't survive one day of use for me.

Ahh, so your EZO bloated too, just took a little longer than mine did.
Sounds like the Mugen (if that's the one you describe getting 9 hours of heavy use) has relatively decent life. Would you say it's significantly better per charge in that respect than the EZO was when it was good?
Also how is the Mugen for longevity, as in not swelling, etc? If I buy a Mugen, would I over the long term pay the same or less than if I had kept buying EZOs? Paying $90 in one blow seems a bit heavy on the wallet, but I'd do it if I'm getting that much better quality & longevity.

Honestly, I got about the same results with my EZO battery: just over 9 hours of constant heavy use. Other than the fact it swelled up, it worked great. I guess there was a reason it was so cheap...
I had a Mugen battery for my Sidekick 4G before I bought the Relay and it still works great. (I loaned the SK4G to a friend that broke his phone.) My new Mugen hasn't had any problems, but I've only had it a few months.
Combined with TeamApex's Cyanogen and this awesome QWERTY keyboard, my extended batteries have made this phone the most productive and useful device I have ever owned. I can't say enough great things about ApexTmo, the Relay, and extended batteries.

[Q] Tips for Non-Removable Battery

Hello all, thanks in advance for any suggestions
I have a Galaxy S5 that I will be taking back to the store since we haven't been able to get root on it yet, fairly satisfied with the phone.
I had an S3 and then a HTC Thunderbolt before that, both with removable batteries.
Removable batteries have been a huge pro for me, I am often very hard on battery using bluetooth and playing media for 12 hours at a time away from charger.
Really other than being a little tall the battery is what is keeping me away from the M8.
What options does a guy have to combat a non replaceable battery? I know the little pocket power cells have come a long way, and I currently always carry a spare battery now so maybe that is a lateral change. Are there some of those that charge very fast?
I tend to keep phones running a LONG time and pass them down to wife/kids and removable battery has always been a big pro to that.

an external battery like you mentioned or a battery case. if you're worried about wearing out the battery, im sure you can replace it manually after 2-3 years by opening up the phone (there's teardowns posted already). I can't speak on either battery option though bc i have a charger at my desk.

The M8 got a very poor repair-ability score from ifixit so a battery swap won't be a simple choice. Thus my being a bit cautious.

Probably no options are needed. I used to carry a spare battery (or two!) for my T-Bolt but found I could live with the S3 and S4 batteries by keeping a spare battery on a charger and swapping batteries around 6 PM each day.
I was VERY nervous about going to the M8 with the non-removable battery but it lasts and lasts and lasts....... I take it off the charger at 7 AM when I get up and have more than 50% when I go to bed, usually around midnight.
I have a car charger, never needed to use it, I have a USB cord plugged into my PC so I can charge while I'm typing this, never do though, it's not needed.
I can't speak to battery life 3 years down the road when cell phone batteries start losing life but in 3 years I suspect this phone will be as obsolete as a rotary dial phone is now and I'll be looking for the latest gee-whiz phone that is cosmic ray powered or ????
Don't worry about the battery, it'll be fine.
FWIW, rooted, TWRP recovery, running BoneStock ROM (thanks, AndyBones!) with power saver turned OFF!

Thanks for the input! Glad to hear very good and optimistic reviews of the power, thanks for sharing what you are running rooted wise and the like, I am missing being able to do that already on the S5.

YW, hope it helps. You know what works for one may not work for another, right?
When Samsung and VZW locked down the S4 (and later the S3) I knew I wouldn't be buying another Samsung phone, us flashaholics GOTTA FLASH!

I was in the same boat as you. I almost went with an S5 because of the non-removable battery. Not being able to remove the battery is a stupid, and lazy, design idea. I watched a few videos about the battery and went for it. I have to say its at least 50% better than my TBolt. At the end of the day my TBolt usually was at about 30-45%. Now with the same exact usage patterns the M8 ends at 98%. Yeah I seem to only use 2% over an 8 hour work day. I use it on breaks of course. I plan on buying one of those portable batteries for emergency charging and I've got at least 3 chargers in various places. I used my phone at a family event for about an hour and a half. I watched 3-4 youtube videos ranging from 10-20 minutes each at max quality and did some web browsing and that brought it to 75%. Tethering with the WiFi Router app can suck it down pretty fast though. All in all Im happy with how well the battery holds up. Im sure someone will sell a better battery you can replace down the road with a little disassembly.

Concerns about a non-removable battery are overblown now days. If you're going to carry around extra batteries, you can just as easily carry around an auxiliary battery. The smaller ones are the size of a lipstick and are rated around 3000 mah, enough to double the capacity of nearly any device currently on the market. If that's not enough for you they go all the way up to 12000 before they start getting too large to carry around. By the time the battery actually needs replacing, you will likely have moved on to another phone.

how do you expect a 90% metal phone to have a removable battery? i don't see this as possible. you're gonna get tabs that break off very easily or something else that fails bc you want to take your battery out easily.
