Tablets with the best battery life

Tablets with the best battery life
We have a new kid on the battery endurance block, and it is Samsung's Galaxy NotePRO tablet. The huge 12.2" slate has an equally impressive 9500 mAh battery, that kept it ticking for nearly nine hours on our demanding battery test. That's more than any other phone or tablet we've tested so far, so we thought we'd share the festivities.

Android tablets are generally expected to last between 8-10 hours of watching HD video on a charge, at medium brightness. Apple's iPads manage to clock 10-12 hours in the same scenario. Until recently, Windows-based tablets were lagging far behind in battery endurance, but with the advent of Intel's new Atom, and mobile Haswell architectures, they managed to almost close in on Android slates.

The NotePRO, however, is in a league of its own, when it comes to battery endurance, and if you want to know the next few tablets in the battery champs category, check out the slideshow below. There are a few new tablets yet to be tested, so these results might be rearranged pretty soon, too.

Nothing interesting to see there. TabPRO 8.4 suffers from poor battery life, based on a lot of reviews. Xperia Tablet Z has even better battery life than that tablet. http://www.engadget.com/2014/03/12/samsung-galaxy-tab-pro-8-4-review/

Sony uses Lithium Polymer to power their Z Tablets, which is more durable than Lithium Ion. Number is not anything.

Lithium polymer battery Limitations -- 1. Lower energy density and decreased cycle count compared to lithium-ion. 2. Expensive to manufacture. 3. No standard sizes. Most cells are produced for high volume consumer markets. 4. Higher cost-to-energy ratio than lithium-ion Source:http://batteryuniversity.com/learn/article/​is_lithium_ion_the_ideal_battery Also check --http://www.androidauthority.com/lithium-ion-vs-l​ithium-polymer-whats-the-difference-27608/ "However, these batteries will cost more to manufacture and have a worse energy density than lithium-ion batteries..." And Nokia phones like 900 and 920 had Li-Poly batteries before the Z tablets.

The way Engadget test a gadget's battery life is stupid. They play a video on loop with 50 percent brightness, They don't consider that brighter display consumes more power than dimmer display. Their review is cool but don't trust their "battery life" number.

For everyone reviewer complaining 6000mah battery is not enough.

+1 for that. Numbers is not the issue here, it's how you use the the tablet. Nexus 7 2013 of mine last for 2 days on regular usage; check mail, subscriptions, social media. 1 day on youtube and heavy gaming like Real Racing 3 and Despicable Me.

What exactly does the battery test consist of?

What about Lenovo? Long lasting battery was supposed to be their main selling point...

Can you give me an example of Lenovo tablet with good battery life along with the source.

Exactly... even the 10-inch version has good battery life. They are coming out with an updated one with Snapdragon processor and better display (called the Yoga HD+). If people still overlook it, they are only selling themselves short. I've seen several articles lately on PhoneArena that ignored Lenovo's prescense in the tablet market.

Bull*hit, my Surface 2 lasts a whole day, longer than the iPad Air .... PhoneArena full of noncense ....

Sorry dude, but GSMArena has the iPad Air beating out the Surface 2 on both Web Browsing and Video Playback tests. The Surface 2 is competitive, no doubt, but the iPad Air still bests it in both battery tests.

Two Question. 1. PA, what kind of methodology do you guys use when you test these tablets? 2. Where is nexus 7's (2013) battery life number?

Impressive for Xperia Tablet Z. Very slim design and quite small battery for its size but perform well. Hoepfully Tavblet Z2 will perform better.

The Galaxy tab has 4500 mAh and the Xperia Tab Z has 6000mAh yet it loses by 20 min... That's decent but not your "impressive"

LOL, are you that simple minded? What about the screen size and hardware?

My Transformer with keyboard dock lasts 15 hours. Yeah, the keyboard dock has an extra battery pack, but I hardly ever use it without the keyboard dock.
