LTE battery life ??

adsam3927 · Mar 31, 2013

Based on the reviews that I've seen in the forums and reviews from tech sites it seems that the One has good not exceptional battery life.
Im in Canada and have international version ordered from Handtec so once I pop in my SIM I'll be on HSPA+ ......(not sure if it supports DC-HSPA like the Nexus 4)
That got me thinking ... If international HSPA version has good battery life then LTE version should probably suck !!:what:
I've seen that there's the option to turn off LTE on phone but then I don't understand the point of holding out for this version ??
I know there haven't been any reviews of LTE model but some feedback would be great .....

Check android hilfe forum. Ppl in Germany on LTE report great battery life. Also you can check other 2 threads here. Few ppl posted screen shots with great battery life on LTE. Like 6h screen on time... 2 days of normal usage.. International version of H1 has LTE and is not limited to USA.

Battery life fine here connecting to lte got 18hrs with 4hours screen on connecting to lte most of the day with about 25% remaining few calls made, lots of music, some you tube, several texts. Very impressed.

Just like the iPhone, is should theoretically use LESS battery on LTE.

Less than what?

Less than using the phone on 2G/3G

iPhone 5 battery is actually a lot better using LTE than 3G. It should be opposite, but I guess Apple really did a good optimization.

Well this is wonderful news .... Thanks
Now I'll wait for the 64Gb developers edition

Well with lower latency and higher speeds, you tax the modem for a shorter period of time, hence the better battery life on LTE. Might seem miniscule at first, but apply the tiny savings to everything you do that uses data and it makes a difference. Or so I understood it from an explanation given on Anandtech. The HTC One should see the same benefits on LTE.

It makes complete sense but when I speak to friends that have the North American LTE enabled s3 they tell me how awful battery life is compared to the i9300 (international HSPA version) ???

You aren't taking into account the completely different SoC. As for the iphome just read anandtech.

And I don't think the international i9300 is that much better in battery life to the LTE US model. They're also using two completely different SoC.

LTE is better for intensive use, 3G is better for standby. In general though the time saved by using LTE means that you come out on top even if the standby is higher.

But dude the chipsets aren't the same.

I don't even know what this means. The One, iPhone 5, Note 2, GS3 Exynos LTE, all GS4 phones, AT&T One X+, Xiaomi MI-2, Optimus G, Optimus G Pro, and Nexus 4 use MDM9x15, which is the same exact modem. Any differences will be on the digital to analog/analog side of the RF chain.

Interesting to note that phonedog did a review on the Sprint LTE version and says battery life is less than international version ...

Most are saying the LTE is equivalent if not slightly better than the non-LTE battery life.

ThePhoneGeek · Apr 10, 2013

Traditionally US LTE networks are horrible for battery life. I've had plenty of devices and for 95% of the time I keep them in 3G (HSPA+ on at&t) because they perform better for battery life.

The LTE networks here are not as advanced and optimized very well so devices tend to have worse battery life.

I have the dev edition on order which I hope will be network selectable and not saddled with at&t's signal meter. The one x and one x+ would only allow network selection if, on a rooted and unlocked bootloader, the standard 3G/H+ signal meter mod was done.

The reason for the poor life is likely low signal quality in your area forcing your phone to constantly switch or look for better signal quality. Generally LTE (in a strong signal zone) will be excellent for your battery because it relies on faster transmission of data -- i.e. less duty cycles -- to complete the same task thus using less power. As I said earlier, it is much like 802.11ac standard now -- faster transmission, less time spent transmitting.

For CDMA/LTE devices, the power draw is due to having multiple radios on-board that need power. When VZW switches to an all-LTE phone by end of this year, it will be much better for their power draw.
