T-Mobile Sidekick 4G Review
Interestingly enough, our callers had no apparent issues on their end of the line comprehending our distinctive voices, but the same cannot be said about the experience on our side. Surprisingly, the earpiece produces some crackly and muffled voices that don’t necessarily provide the most audible calling experience. Moreover, the same experience is evident with the handset’s speakerphone as well – which renders it almost incapable of carrying out a lengthy conversation.

Riding steadily at -77 dBm of signal strength in high coverage areas, we didn’t experience any abrupt movements during our testing – nor did it drop any calls as well in the greater Philadelphia region.

Even though we managed to pull through a solid 8 hour work shift without the need to charge the handset one bit, we’re rather unimpressed with its battery life. After charging it fully, we rigorously used the Sidekick 4G and managed to reach the 10 hour mark before it tapped out completely. Considering that it’s a messaging oriented device, you’ll probably want to consider juicing it up whenever possible to avoid finding yourself phoneless.


Rising back from a shallow grave, the T-Mobile Sidekick 4G has enough fuel in its tank to supremely live up the expectations brought on by previous devices. Still embodying and placing a lot of attention on some of its beloved prime features, there’s no denying that this modernized Sidekick will undoubtedly keep up with the demanding needs of the no talk and all messaging personalities of today’s youth. At $99.99 on-contract, the T-Mobile Sidekick 4G has plenty of admirable features and specs to keep its head above water against some of the competition. Granted that it isn’t the best looking Sidekick we’ve seen, we’re more than pleased with the drastically customized Android experience and its bevy of messaging oriented services that are no doubt appreciable on so many levels.

Software version of the reviewed unit: Android 2.2.1, Build FROYOO.UVKD1

So 10 hours of heavy 4g usage is poor battery life? Maybe I'm just used to the poor battery life I get with my G1, but that seems pretty fantastic to me. Considering this phone, even though I'm not the target demographic

Yea that seems kinda odd considering. I wish my TB got 10 hours of battery life PERIOD. 3G DOESNT.

I'm curious if flash 10.2 was installed by an upgrade? If not then that's why you got the jitters because you really need Flash 10.2!!

10 hours of battery life is outstanding from any 4G phone. I get only 3 hours on my Samsung Epic 4G!!

I had to purchase a 3000 mAH battery and now it's .8 inches thick!

So do your homework reivews and compare apples to apples like the Samsung Epic 4G to this phone!

It may not be able to compete with the top tier phones out there, but the Sidekick 4G is still an excellent choice for heavy messaging and/or social networking users. Hey we are going to aggregate your review and bring more people directly this link. Come check us outwww.technado.com

i don't understand why just because the sidekick 4g has the android platform, it needs to compete with top tier phones. i honestly think it's targeting a different market than that. this is a very differently designed phone compared to the top tier, so why should it have to compete in all other aspects?

This phone is still the only choice for me. TMobile is the only carrier that works in my house. Even considering other carriers, there is not too many side-sliders with a 5-row hardware keyboard, and I won't live without that. This is the only one that has raised edges when open (like the G1) and that makes it way easier to hold. It also has hardware buttons which I greatly prefer. I get ~30hours of normal-use battery, and >10 with very heavy 4G use. If it were dual-core, had a better camera with flash, and had a bigger/better display, it would be the ultimate phone!
