The Inbox: ASUS Zenfone 2 Not Having Removable Batteries

ASUS Zenfone 2 ZE551ML 10

After publishing our first article under “The Inbox” we got a barrage of messages on the Unbox Facebook Page. We’re trying to comb through all of them and pick the ones that we can quickly answer and help resolve. For today’s entry we’re going to go up close and personal with an upcoming smash hit smartphone, the ASUS Zenfone 2.

“Hello Unbox! Bakit po yung ZF2 walang removable battery and micro SD card? Sayang naman. Ganda ng specs pero pilit copya sa iPhone.” -Raymart R.

Our answer to Raymart after consulting with our friends from ASUS PH:

First, the ASUS Zenfone 2 has a micro SD card slot. The back plate is removable and you can slide in a micro SD card with your favorite movies and tracks.

However the battery is indeed NOT removable. The reason for this is that ASUS users a Lithium Polymer battery (the current is sensitive thus the cover) and not the usual Lithium Ion.

Lithium Polymer vs Lithium Ion

Polymer batteries have distinct advantages over Lithium Ion. According to ASUS PH, Polymer batteries gives 3x more charges than Lithium Ion. This means that Polymer batteries won’t degrade in quality and power as fast as Lithium Ion batteries do. It’s more sustainable and efficient in the long run.

More importantly, the Lithium Polymer battery is required for fast charging which the 2.3GHz ASUS Zenfone 2 model has. Personally we would rather have fast charging than a replaceable battery so we think it was a good move by ASUS to go with the Lithium Polymer.

And that’s a wrap! Hope we were able to answer your question Raymart! Thank you also to the people from ASUS for the quick reply to our questions.

  1. meh… couldn’t follow up on the hype of the zf5. released too late and the only way to salvage the success is to have it’s 2gb version a sub 8k pricing.

    1. The hype is with its 4gb-ram version, not the 2gb one. It’s not so much for the budget-tight, as it certainly would get way past the 10k-php mark. But with a little budget strech, the ZF2 (4gb-ram) can trump even the Samsung Galaxy Note 3 and LG G3 in raw performance, for about half the price (sub-15k). You’ll be hard-pressed to find a better bang for your buck. That’s what the hype is about.

  2. follow up question… in case the battery goes out for whatever reason, will asus centers be able to repair/replace the battery? or will the phone end up trash?

        1. thanks for the reply but it doesn’t seem to answer the question.. so since you are assuming that the battery will go out AFTER asus releases another phone then am i right to assume that if the battery goes out BEFORE any phone release then the phone cant be repaired?

  3. Hi guys, need some advice please. If you could buy Asus Zenfone 2 (4GB RAM version, with 32GB ata) and LG G3 (16GB only) at the same price, which one would you choose? Anong pros and cons para sa inyo? Thanks in advance sa magko-comment. 😀

    1. Lg has better camera for taking videos and focusing is faster in lg….but Asus has better processer and ram…I have bought Asus so I am biased….end of day buy a phone which feels comfortable in your hand
