Im looking for an X1 replacement batter with the charger. I have this same exact thing for my HTC Touch Cruise and believe me it is a godsend. Instead of sitting there for my phone to charge, I have one in the dock charging all the time. So when I run low to dead just swap and in seconds I have new juice.

http://cgi.ebay.com/1350mAh-Battery...14&_trkparms=72:1205|66:2|65:12|39:1|240:1318
unless your a really power user you probably won't need to charge the battery that often given hercules is powering the x1 i think with heavy use you'd be good charging it probably once every 10-12 hours
What about with WiFi use?
I know on my Wizard the battery goes in about 2 hours with WiFi active even if its just idling with Messenger. Have they actually improved that much over the years? I'm hopeful but also skeptical.
WMVWifiRouter will kill your battery in an hour and a half.
I'd be curious to know if there are any reliable aftermarket batteries. Buying any Sony OEM parts are always ridiculously expensive and many aftermarket batteries don't work well with Sony products.
well based on what i've been reading about the X1 it's supposed to have a nice increase in battery life compared to our current HTC phones. supposedly sony made a special project just for the phone codename Hercules it's supposed to be using a 1800 mah li poly in stead of what we use in our current phones which is li ion supposedly using the li poly is going to give the battery a much needed boost that all ppc's need to go all day or maybe a couple of days given the usage
Li-poly batteries is over 20% higher than that of a classical Li-ion battery and they store more energy than nickel-cadmium (NiCd) and nickel metal hydride (NiMH) batteries of the same volume.
When compared to the lithium-ion battery, Li-poly has a greater life cycle degradation rate. However, in recent years, manufacturers have been declaring upwards of 500 charge-discharge cycles before the capacity drops to 80% (see Sanyo). Another variant of Li-poly cells, the "thin film rechargeable lithium battery", has been shown to provide more than 10,000 cycles.

I was reading about Li-Po battery's, and I found out that these batteries might over-charge and go ka-boom.
Is this true? Does anyone have any knowledge with these batteries, and is this at all a Draw back for the N4?
Edit: Okay, so I was just scoping around and I think this source might be incorrect, but it seems like recharging these batteries have precautions, like certain time-limits. Maybe this is for removable batteries, but none the less these batteries seem more complicated than Li-Ion.
Here's a guide for charging Li-Po's that states overcharging is bad: http://www.ehow.com/how_6049668_method-charge-lithium-polymer-battery.html

Aren't Li-poly batteries actually safer than Li-ion?
That's the Technology used on Mac Book Pros and the iPads ... They are supposed to have faster and longer charging cycles among other advantages like being lighter and have more accurate power readings... But i could be wrong so please correct me if I'm misinformed ?

See that's what I tough too ?
Don't wanna start a war here but the battery on my new iPad it's fantastic ! Even on LTE I get like 2 days plus of heavy use..
LiPo or Lithium polymer batteries have a much higher power/weight/size ratio then typical Li-Ions, which makes them awesome for portable devices. The downside is that they are very temperamental as far as discharging and charging goes. Cells need to be leveled and managed independently when charging, punctures in the battery can cause it to catch fire, and have been known to create explosive fireballs when overcharged.
While it is true that over-charging a LiPo can make it catch fire, there will be controllers in place to prevent this from happening. These things are quite fussy. Even letting a LiPo drain below a certain percentage can be detrimental to the health and longevity of the battery, 20% of the battery's total capacity is often regarded as the minimum safe charge. It is also recommended to keep a 50-60% charge in a LiPo if storing it for long periods of time.
Fortunately, there will be a LiPo controller on the phone which will manage all of the dirty work for us. I imagine a ~20% charge on the LiPo will be regarded as 0% for the phone, as to not allow the battery's voltage to drop too low. Charging will be managed with independent cell leveling, and it will make sure the battery is not over-charged.
I really do not believe that, as a consumer we will have to worry about the battery or how its charging. We will just get to enjoy the awesome battery life associated with the LiPo.
Awesome thanks for clearifying it for me. You said that 20 percent might equal 0, so does that mean 2100mah will be cut short?
LiPo batteries are awesome. I still have my SE K750i and the battery life, despite over 4 years of use, is still amazing. I don't use it anymore but the battery still seems to keep most of a full charge unlike other cell phones (Siemens C65) which cant even maintain enough charge to power on after charging.
I don't think you would have to worry about the 2100mAh rating... I fiddled around with RC vehicles before and I ran one off of a parallell pack of Lipos, that should equal 10Ah which gave me about 1 hour and 45 minutes of "play time" with my truck(brushless outrunner motor and a mamba monster). It should be noted that after those 1 hour and 45 minutes the batteries still held up pretty well but the motor was glowing hot, never had any troubles with anything until I torched the motor because of the prolonged runtimes I was getting...
http://youtu.be/0Yg88tg71m4
Interestingly, if you go into device info (*#*#4636#*#*) and hit battery information, it lists the battery as using Li-Ion technology, can anyone else confirm this? If so, there may be more to this than just a LiPo battery.
We all know that the One (and many other modern cellphones) have a Lithium Ion battery. While these batteries have no traditional 'memory effect' the way NiMH did, it seems that different chemistries for the electrolyte would suggest different strategies for recharging.
For example, after looking at the Wikipedia entry for Lithium batteries, it would seem that we should be mindful about 'topping off' the battery, because charging deteriorates the lifespan, implying that running down the battery might be a more advisable practice than plugging in to fully charge every night.
Wondering if any of you experts out there can comment and discuss, given that we One users no longer have replacable cells.
Good question, I too would be very interested in hearing from some of the posters that are knowledgeable in this area.

This is pretty well established knowledge right now. I'll list everything pertinent about lithium ion batteries and charging smartphones:
Edit: Note that I mention Lithium Ion in this post, but the HTC One uses Lithium Polymer. They are for all intents and purposes equal in terms of their usability, except for slightly less charge cycles
Edit 2: Hello Reddit! No idea this would have taken off. I'm "coolmatty" on reddit. This is an overall generalization, and there are plenty of resources that go into more detail. Places like Battery University are great sites to start.
1. Charging is what reduces the life of a lithium ion battery. Batteries are usually rated between 700-1000 charge cycles while keeping 90% of their capacity.
2. Charging 0-100% counts as one cycle. Charging 80-100% 5 times counts as one cycle.
3. Leaving your phone on the charger after it is charged has the potential to reduce battery life, although this is less of a problem with newer devices as they often disconnect the charging circuit until the battery drops below ~95%. Generally only an issue if you leave it on the charger for 24+ hours.
4. Lithium ion batteries do not require any conditioning.
5. Most lithium ion devices arrive with ~40-50% battery life remaining, because this is the optimal charge level to store a lithium battery for long periods (such as sitting on a store shelf for months).
6. Slower charging maintains the battery's overall lifetime capacity better than fast charging. This is likely why the HTC One does not have Qualcomm's Quick Charge enabled. It's debateable whether you'd notice the effects over the typical lifetime of a smartphone, however (2 years).
7. Not exactly related to lithium but just in general: smartphones (and tablets, etc) have charging circuits that only draw a certain amount of amps regardless of the number of amps the charger provides. Using a 3.1 amp (tablet-level) charger is not going to significantly increase the speed at which your phone charges. Most phones only use between 0.8 - 1.2 amps. Anything over that is overkill.
8. Storing a lithium ion battery at 0% is really bad for its lifetime capacity. Running it to 0% generally isn't recommended all the time, but a few instances won't hurt it.
9. Recharging from 0-100 doesn't make your battery run longer. It can, however, reset Android's battery level stats so that it can more accurately state the battery level.
10. Charging from ~95% to 100% takes a long time because it must do a trickle charge. Maxing out the battery like this can reduce overall lifetime capacity, but generally not enough to matter. You'll see this impact more often in larger applications of lithium batteries (like cars).
You have no idea how many people need this post (on some points, myself included). Thanks.

It does not seem to be that uniform, according to this:

From what I understood from the link above in Table 2, you can get the best longevity by charging from 50% (2nd row).

What is a practical approach for me now, after reading this all, is to charge it every night.
This way
- I have better chances for not running out of battery during the day
- either it was at 75% (3rd row) or 50% (2nd row) I still have better longevity than charging from 0% most of the time.
Battery life will not degrade as long as you donot empty its charge for long time and donot use it while on charge... over heat on battery aged the battery...

Just wanted to add: li-ion and li-po batteries now-a-days have protection circuitry to prevent overcharge and over-discharge. Overcharge protection based on what is stated above, known as trickle charge. Over-discharge protection means that your phone will shut off when your battery is around 3v per cell, whereas you should refrain from force starting the phone. The only benefit you get from fully charging/discharging is battery calibration for cell mismatches. It is also good to know that partial charges are better than full charges when it comes to lithium ion (and lithium polymer) batteries.
The HTC one uses li-poly, not li-ion
Can read all about the advantages and disadvantages of each other here:
http://batteryuniversity.com/learn/article/is_lithium_ion_the_ideal_battery
li-poly
Advantages
Very low profile - batteries resembling the profile of a credit card are feasible.
Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Limitations
Lower energy density and decreased cycle count compared to lithium-ion.
Expensive to manufacture.
No standard sizes. Most cells are produced for high volume consumer markets.
Higher cost-to-energy ratio than lithium-ion

As far as I am concerned, li-poly is overall better for phones where you can't change the battery.
by the looks of that article it was done quite a while ago (for the tech. world) so the disadvantages might not be as much of a problem these days.....

I was using a simplification. It would be better not to let it go to 0, but most charge cycles are rated on this. I do mention the impact of letting the battery go to 0%.

A flub on my part, you are correct. There are minor differences (the only one that matters to us is slightly shorter lifetime capacity) but otherwise it works the same.
Now that i see a battery 'expert', a quick question.
Back in the dack, if you bought anything with batteries, you would have to charge them for 24h, no matter how much charged they were. But if i were to buy a phone today (Lith-Ion), Do i still have to do that?
I think not, but i'm not quite sure. Lots of people (even smartphone sellers) still recommend charging it 24h, wich i think is bull.

I'm not sure everyone noticed one of the things he said. I know from my HD2 and Ruby that HTC phones will not continue charging after hitting 100%. The phone will indicate %100, but shortly after you disconnect the charger and start using the phone the indicated power level will drop to what it actually is - and it will be lower depending upon how long it has been sitting at "100%". Their phones have a protection circuit that kicks in. So if you really want 100% in the morning, power the phone down to charge it.

As I mentioned in my first post, Lithium batteries do not require conditioning. The purpose for this on old Ni-Cad batteries was to avoid the memory effect, which could result in a battery appearing to be dead long before it actually was. For instance, if you always charged it from 60%, after many instances of this, the Ni-Cad battery would suffer a voltage drop at that point, which most electronics can't handle (some can, however, and once past the short period of low voltage, they will recover and continue normally).
Charging for 24 hours is most certainly not relevant, as once the battery reaches 100%, charging has ceased anyway. There's no need to charge it to 100% anyway, other than to give you more time to play with your new toy

You'll see this in most devices nowadays. It's especially noticeable on laptops, which typically won't lie to you about the charge. It depends on the models, but I know Macbooks for instance will happily sit at 95% charge as "fully charged". This is by design and other than turning off the device, you shouldn't try to "top it off". Any other method (such as unplugging and plugging it back in) hurts the overall lifetime of the battery.

Most of the modern laptops allow you to turn on or off the battery saving feature. For those who use the laptop while plugged in most of the time, it will stop charging at 80%. For those who will be using it off the plug, the option is there to get it to 100%.

I've never heard of this, and I don't recall seeing it on any Windows or Mac laptop I've used recently. Sounds like some proprietary crap one of the manufacturers came up with. Stopping the charge at 80% doesn't make much sense, since you'll still have the issue of constantly recharging the battery (as soon as it drops below 80%).
Edit: I will say that it is marginally better than keeping it at 100%, but that said, there's steps you can take on your own that are much better.
The ideal way to use a laptop that will be plugged in for most of its lifetime is to discharge it to about 45%, and then remove the battery entirely. At that point, the battery can maintain its capacity for months without major issue. Just make sure to recharge it once every 3 months or so, as the battery will discharge (slowly) even while unplugged, but at a far slower rate than it would be inside the laptop.

The latest research from the Auto manufacturers is that Li-Ion technology works longest if the battery level is between 50 and 80%.
My Toshiba U925 ultra portable uses the optional 80% max. If you use the laptop almost exclusively while plugged in, it will help provide battery longevity, or so I understand.
Many laptops won't work unless the battery is in place. It depends on how they built the power circuits.
http://pocketnow.com/2013/05/03/li-ion-batteries-memory-effect
We all know how important batteries are in our modern electronics. They’re also becoming an increasingly vital part of our vehicles. For people in both camps, the latest news from Toyota is disheartening: Li-Ion batteries have a “memory effect”.
Ni-Cad Batteries
When the traditional, land-line telephone evolved from a corded beast into a clunky — but wireless — beast, there was much cause for celebration. The battery technology of the day was Ni-Cad (Nickel Cadmium). Batteries based on this technology were used in everything from cordless phones to satellites orbiting the planet. There were two significant problems that plagued these batteries.
First, after thousands of charge/discharge cycles to within 2% of the same state of charge, the battery would develop a “sudden drop” in voltage. To many electronic devices, this drop would make the battery appear “dead”. NASA figured this one out because their batteries could only be charged when the sun was shining on panels, and the satellites usually used the same amount of energy to power them while they were in Earth’s shadow. It’s extremely unlikely that any consumer electronic device would be subjected to conditions that would reproduce this problem. Scientists at GE’s Battery Business Department in Gainesville, Florida published a paper describing the “memory effect”, but didn’t convey that Earth-bound consumers should never run into this condition, and later retracted their paper, but the damage in the public-eye was already done.
VGER
What kind of battery technology powers V’GER?
Second, there was another issue with Ni-Cad batteries that presented symptoms similar to that discovered by NASA and GE: “voltage depression” or “lazy battery effect”. This results from repeated overcharging, but can generally be “fixed” by subjecting the battery to a few deep cycles.
Eventually new technologies were introduced, eventually bringing us to today’s Li-Ion and Li-Polymer batteries. Unfortunately, to the typical end-user who wants their electronics to be fully-charged, keeping the battery on the charger for extended periods of time only increases the effect, and makes the usable per-charge lifespan of the battery lower — even with the new technology.
Li-Ion Batteries
Lithium Ion and Lithium Polymer batteries are found in almost every electronic device today. Cell phones, smart watches, and even hybrid and electric vehicles are powered by these technological gems. According to a new study, even our latest and greatest battery technology isn’t immune from the dreaded “memory effect”, though you’re not as likely to see it as you were with Ni-Cad batteries. That’s the good news.
Samsung Li-Ion Battery
The battery inside your cell phone is likely Li-Ion
There’s a lot of physics and technical information behind why batteries present this “memory” when discharging, and if you’re interested in all that, I highly recommend the article at Phys.org that I’ve linked below. For this article, however, suffice it to say that Li-Ion has the same problem as older battery technologies, just not as visible. Luckily, the “solution” is the same today as it was two decades ago.
How to Defeat the Memory Effect of Li-Ion Batteries
We’ve all got to realize that we can’t get rid of the “memory effect” problem. It’s inherent to the technology — and likely to batteries in general. But now that we know about it, we can adapt and minimize the impact the “memory effect” has on our electronics. It’s fairly simple, which may be one reason why it’s not widely adopted. Keep the following rules in mind:
Realize that your batteries don’t like to live at the very top or the very bottom of their charge capacity. Don’t keep your devices on the charger after they’re fully charged. Similarly, don’t leave them dead in a drawer for expended periods of time either.
Every once in a while, completely discharge your device, then completely charge it up again. Do that a few times in a row. This will help “condition” the battery and will ensure that you get better use of its capacity. Doing this will reduce the rated lifespan of the battery, but it will get you more practical use out of it and prevent a premature death.
That’s it. Pretty simple, right? Ironically that’s what HAM Radio operators have been telling us for many decades, and those guys really know their stuff!

Think of it as listening to a podcast on the way to work.
Not asking the obvious here.
I'm wondering if I can replace the battery a year or two down the line, assuming I have a respectable arsenal of tools. I know batteries wear out, and I'd like to keep this phone alive as long as I can.
Was wondering this as well. I watched a takedown vid and it appears like the battery is molded for formed into part of the rear framework or something. They didn't show it being removed. But you can get to it so someone will probably make a replacement I'm guessing.
Video I saw, battery looks like a bear to replace.
Can it be done? Yes. Is it worth it? The answer to that question depends on this IMO: Will you be able to buy a FRESH new/unused battery with performance and safety certification at least as good as the original, two years from now (one year after XT1575 production ends)?
Don't overlook the FRESH (chronological age) aspect. Li-Ion batteries start losing capacity the moment they are manufactured, typical estimates are about 70% of fresh capacity or less after 2 years and dropping further over time. Even if battery sits unused in new package on a shelf the whole time.
And don't overlook the performance and safety either. Aftermarket batteries are a dice roll on both counts.

Anker is a good company in my experience.
But: Can you confirm the date of manufacture of Li-Ion batteries they sell?
I have never been able to get a straight answer on the date of manufacture of aftermarket Li-Ion cellphone batteries from sellers or manufacturers, and even most OEM batteries do not provide this information to the end user (or it is coded in markings on the battery and the end user cannot get the secret decoder ring).
Since Li-Ion batteries have a chronological life limit of about 2-3 years, with capacity dropping below 70% typically by 2 years regardless of service or duty cycles, this is important information. And I believe that the reason you cannot get this freshness information is because replacement Li-Ion cellphone batteries are all stale.
I too have replaced cellphone batteries and "had no problems". But they were stale OEM or aftermarket batteries, and not as good as fresh new OEM. This is a dirty little secret of the aftermarket Li-Ion cellphone battery market.
2 year product life cycle. Rapidly diminishing returns after that. See the product life cycle, be the product life cycle.
